Exercise 14 Page 844

Use the formula for the volume of a pyramid.

1376.7 ft^3

Practice makes perfect

The volume of a pyramid can be calculated using a known formula. In this formula B is the area of the base, and h is the height of a pyramid. V=1/3Bh In our exercise we are given that the base area is 590ft^2 and an altitude is 7 ft. Let's substitute these values into the formula and calculate V.

V=1/3Bh

SubstituteII

B= 590, h= 7

V=1/3( 590)( 7)
