Exercise 30 Page 626

We are told that hexagonal pyramid has a base measuring 212cm^2 in area and a height of 17cm. With this in mind, we want to find its volume. To do it, we can use the following formula. V=1/3Bh In this formula, B is the area of the base, and h is the height of the pyramid. Let's substitute the area of the base and the height of the pyramid into the formula and calculate V.

V=1/3Bh

SubstituteII

B= 212, h= 17

V=1/3( 212)( 17)
