Exercise 25 Page 873

Use the formula for the volume of a pyramid.

91 636 272 cubic feet

Practice makes perfect

The Great Pyramid can be modeled by the following right square pyramid with a height of h= 481 feet and a base side length of s= 756 feet.

We are asked to find the volume of the pyramid. Let's use the formula for the volume of a pyramid. V=1/3 B h Here, B is the area of the base. Since the base is a square with the side length of s= 756 feet, its area is B= 756^2= 571 536 square feet. Now, let's find the volume of the pyramid.

V=1/3 B h

SubstituteII

B= 571 536, h= 481

V=1/3( 571 536)( 481)
