Question

The base of a pyramid covers an area of 13.0 acres (1 acre = 43,560 ft^2) and has a height of 481 ft. If the volume of a pyramid is given by the expression V = (1/3)bh, where b is the area of the base and h is the height, find the volume of this pyramid in cubic meters.

_____m^3

Thanks for any help!!!

Answer 1

first convert to M;; 13 acres=52609.13M^2;;481'=146.6M.Then substitute so 52609.13/3=17536.38 *146.6=2,570,833M^3

Answer 2

Is this a square base pyramid or a triangular base pyramid?

But the same equation works for both

V = (1/3)bh

working in ft

V = (1/3)(13*43,560)(481) = 9.079e+7 cubic ft

or 2.571e+6 cubic meters
