Find the volume of the following. Please round your answer to the nearest tenth. Please do not put units. Hint: You need to use
Sophie [7]

Answer:

<em>V = 1,568</em>

Step-by-step explanation:

<u>The Volume of a Square Pyramid</u>

Given a square-based pyramid of base side a and height h, the volume can be calculated with the formula:

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

We are given a square pyramid with a base side a=14 ft but we're missing the height. It can be calculated by using the right triangle shown in the image attached below, whose hypotenuse is 25 ft and one leg is 7 ft

We use Pythagora's theorem:

25^2=h^2+7^2

Solving for h:

h^2=25^2-7^2=625-49=576

h=\sqrt{576}=24

The height is h=24 ft. Now the volume is calculated:

\displaystyle V=\frac{1}{3}*14^2*24

V = 1,568
