Exercise 23 Page 659

We want to find the volume of an ancient stone pyramid. This pyramid has a square base with a side length of 16.5 meters. It is 13.6 meters tall. We can calculate the volume of a pyramid using the following formula. V=1/3BhHere, B is the area of the base, and h is the height. The base of our pyramid is a square with a side length of 16.5 feet. Its area B is a square of the side length. Let's find it! B= 16.5^2 = 272.25 The base's area B is 272.25 square meters. The height h is 13.6 meters. Let's substitute these values into the formula and calculate V.

V=1/3Bh

SubstituteII

B= 272.25, h= 13.6

V=1/3( 272.25)( 13.6)
