Question

A pyramid has a height of 455 ft and its base covers an area of 12.0 acres (see figure below). The volume of a pyramid is given by the expression

V =1/3Bh

where B is the area of the base and h is the height. Find the volume of this pyramid in cubic meters. (1 acre = 43,560 ft²)

science physics

Answer 1

Answer #1

1ft = 0.3048 m 1 ft^2 = 0.0929 m^2

Height of pyramid h = 455 ft = 138.68 m

Base area B = 12 acres = 12*43560 ft^2 = 522720 ft^2

= 48562.28 m^2

Volume of pyramid V = 1/3 Bh = 48562.3*138.7 / 3

= 2244872 m^3
