Introduction

The formula for the volume of a right square pyramid is a fundamental concept in geometry, and it is essential to understand how to manipulate this formula to solve for different variables. In this article, we will focus on rewriting the formula to solve for the side length 'a' of the base of the pyramid. We will examine the given options and determine the correct solution.

The Formula for the Volume of a Right Square Pyramid

The formula for the volume of a right square pyramid is given by:

${ V = \frac{1}{3} a^2 h }$

where V is the volume of the pyramid, a is the side length of the base, and h is the height of the pyramid.

Solving for 'a'

To solve for 'a', we need to isolate 'a' on one side of the equation. We can start by multiplying both sides of the equation by 3 to eliminate the fraction:

${ 3V = a^2 h }$

Next, we can divide both sides of the equation by h to get:

${ \frac{3V}{h} = a^2 }$

Now, we can take the square root of both sides of the equation to solve for 'a':

${ a = \sqrt{\frac{3V}{h}} }$

Evaluating the Options

Let's examine the given options and determine which one matches our solution:

A. ${ a = 3 \sqrt{\frac{V}{h}} }$

B. ${ a = \sqrt{\frac{3 h}{V}} }$

C. ${ a = \sqrt{\frac{3V}{h}} }$

Based on our solution, we can see that option C is the correct answer.

Discussion

The formula for the volume of a right square pyramid is a fundamental concept in geometry, and it is essential to understand how to manipulate this formula to solve for different variables. In this article, we have shown how to rewrite the formula to solve for the side length 'a' of the base of the pyramid. We have also evaluated the given options and determined the correct solution.

Conclusion

In conclusion, the formula for the volume of a right square pyramid is given by:

${ V = \frac{1}{3} a^2 h }$

To solve for 'a', we can multiply both sides of the equation by 3, divide both sides by h, and take the square root of both sides. The correct solution is:

${ a = \sqrt{\frac{3V}{h}} }$

This formula is essential in geometry and is used to calculate the side length of the base of a right square pyramid given its volume and height.

Additional Examples

Here are a few additional examples of how to use the formula to solve for 'a':

If the volume of a right square pyramid is 100 cubic units and its height is 5 units, what is the side length of the base?
If the side length of the base of a right square pyramid is 4 units and its height is 6 units, what is the volume of the pyramid?

To solve these problems, we can use the formula:

${ a = \sqrt{\frac{3V}{h}} }$

We can plug in the given values and solve for 'a'.

Real-World Applications

The formula for the volume of a right square pyramid has many real-world applications. For example, it can be used to calculate the volume of a pyramid-shaped building or a pyramid-shaped container. It can also be used to calculate the volume of a pyramid-shaped rock or a pyramid-shaped mountain.
