Exercise 56 Page 10

How does the height help you to find the volume of a pyramid?

h=3.5ft

Practice makes perfect

To find the volume of a pyramid we use a formula that relates the pyramid's height h and its base area B. V=1/3Bh From the figure, we are given the volume V= 35ft^3 and the base area B= 30ft^2 of a pyramid. By substituting these values into our equation, we will be able to use inverse operations to determine the value of h.

V=1/3Bh

SubstituteII

V= 35, B= 30

35=1/3* 30* h

1/b* a = a/b

35=30/3* h
