Introduction

In this article, we will explore the process of constructing a building using bricks that can be modeled as right rectangular prisms. We will calculate the volume, weight, and cost of these bricks, which will be essential in determining the overall cost of the building. The dimensions of the bricks are given as $8 \frac{1}{4}$ in by $2 \frac{1}{4}$ in by $3 \frac{1}{4}$ in, and they weigh 0.05 ounces per cubic inch.

Calculating the Volume of a Single Brick

To calculate the volume of a single brick, we need to multiply its length, width, and height. The formula for the volume of a rectangular prism is:

V = lwh

where V is the volume, l is the length, w is the width, and h is the height.

First, we need to convert the mixed numbers to improper fractions. The length is $8 \frac{1}{4}$ in, which can be converted to an improper fraction as follows:

8 \frac{1}{4} = \frac{(8 \times 4) + 1}{4} = \frac{33}{4}

Similarly, the width is $2 \frac{1}{4}$ in, which can be converted to an improper fraction as follows:

2 \frac{1}{4} = \frac{(2 \times 4) + 1}{4} = \frac{9}{4}

The height is $3 \frac{1}{4}$ in, which can be converted to an improper fraction as follows:

3 \frac{1}{4} = \frac{(3 \times 4) + 1}{4} = \frac{13}{4}

Now, we can calculate the volume of a single brick by multiplying its length, width, and height:

V = lwh = (33/4) × (9/4) × (13/4) = (33 × 9 × 13) / (4 × 4 × 4) = 4095 / 64 = 63.828125 cubic inches

Calculating the Weight of a Single Brick

The weight of a single brick is given as 0.05 ounces per cubic inch. To calculate the weight of a single brick, we need to multiply its volume by its weight per cubic inch:

Weight = Volume × Weight per cubic inch = 63.828125 cubic inches × 0.05 ounces/cubic inch = 3.19140625 ounces

Calculating the Cost of a Single Brick

The cost of a single brick is not given, but we can assume that it is a fixed cost per brick. Let's assume that the cost of a single brick is $x.

Calculating the Total Volume, Weight, and Cost of the Building

To calculate the total volume, weight, and cost of the building, we need to multiply the volume, weight, and cost of a single brick by the total number of bricks used in the building.

Let's assume that the building uses 1000 bricks. The total volume of the building is:

Total Volume = Volume of a single brick × Number of bricks = 63.828125 cubic inches × 1000 = 63828.125 cubic inches

The total weight of the building is:

Total Weight = Weight of a single brick × Number of bricks = 3.19140625 ounces × 1000 = 3191.40625 ounces

The total cost of the building is:

Total Cost = Cost of a single brick × Number of bricks = $x × 1000 = $1000x

Conclusion

In this article, we calculated the volume, weight, and cost of a building constructed using bricks that can be modeled as right rectangular prisms. We used the dimensions of the bricks to calculate their volume, weight, and cost, and then multiplied these values by the total number of bricks used in the building to determine the total volume, weight, and cost of the building. The results show that the total volume of the building is 63828.125 cubic inches, the total weight is 3191.40625 ounces, and the total cost is $1000x, where x is the cost of a single brick.

Calculating the Cost per Square Foot of the Building

To calculate the cost per square foot of the building, we need to divide the total cost of the building by the total square footage of the building.

Let's assume that the building has a total square footage of 10000 square feet. The cost per square foot of the building is:

Cost per square foot = Total Cost ÷ Total Square Footage = $1000x ÷ 10000 = $0.1x

Calculating the Cost per Square Inch of the Building

To calculate the cost per square inch of the building, we need to divide the total cost of the building by the total square footage of the building, and then divide the result by the total number of bricks used in the building.

The total square footage of the building is:

Total Square Footage = Total Volume × 12 = 63828.125 cubic inches × 12 = 766736.5 square inches

The cost per square inch of the building is:

Cost per square inch = Cost per square foot ÷ Total number of bricks = $0.1x ÷ 1000 = $0.0001x

Introduction

In our previous article, we explored the process of constructing a building using bricks that can be modeled as right rectangular prisms. We calculated the volume, weight, and cost of these bricks, which will be essential in determining the overall cost of the building. In this article, we will answer some frequently asked questions related to the calculation of volume, weight, and cost of the building.

Q: What is the formula for calculating the volume of a rectangular prism?

A: The formula for calculating the volume of a rectangular prism is:

V = lwh

where V is the volume, l is the length, w is the width, and h is the height.

Q: How do I convert a mixed number to an improper fraction?

A: To convert a mixed number to an improper fraction, you need to multiply the whole number part by the denominator and add the numerator. Then, you divide the result by the denominator.

For example, to convert $8 \frac{1}{4}$ to an improper fraction, you would multiply 8 by 4 and add 1, which gives you 33. Then, you divide 33 by 4, which gives you $\frac{33}{4}$ .

Q: How do I calculate the weight of a single brick?

A: To calculate the weight of a single brick, you need to multiply its volume by its weight per cubic inch.

Weight = Volume × Weight per cubic inch = 63.828125 cubic inches × 0.05 ounces/cubic inch = 3.19140625 ounces

Q: How do I calculate the cost of a single brick?

A: To calculate the cost of a single brick, you need to multiply its volume by its cost per cubic inch.

Cost = Volume × Cost per cubic inch = 63.828125 cubic inches × $x/cubic inch = $3.19140625x

Q: How do I calculate the total volume, weight, and cost of the building?

A: To calculate the total volume, weight, and cost of the building, you need to multiply the volume, weight, and cost of a single brick by the total number of bricks used in the building.

Total Volume = Volume of a single brick × Number of bricks = 63.828125 cubic inches × 1000 = 63828.125 cubic inches

Total Weight = Weight of a single brick × Number of bricks = 3.19140625 ounces × 1000 = 3191.40625 ounces

Total Cost = Cost of a single brick × Number of bricks = $3.19140625x × 1000 = $3191.40625x

Q: How do I calculate the cost per square foot of the building?

A: To calculate the cost per square foot of the building, you need to divide the total cost of the building by the total square footage of the building.

Cost per square foot = Total Cost ÷ Total Square Footage = $3191.40625x ÷ 10000 = $0.319140625x

Q: How do I calculate the cost per square inch of the building?

A: To calculate the cost per square inch of the building, you need to divide the total cost of the building by the total square footage of the building, and then divide the result by the total number of bricks used in the building.

Cost per square inch = Cost per square foot ÷ Total number of bricks = $0.319140625x ÷ 1000 = $0.000319140625x
