Question

Find the volume of a pyramid with a square base, where the side length of the base is
12 ft and the height of the pyramid is 7.1 ft. Round your answer to the nearest tenth
of a cubic foot.

Answer 1

Answer:

The volume of the given pyramid is 340.8 cubic feet.

Explanation:

The volume of an object is a consideration of the dimensions of the object with respect to 3 dimensions.

volume of a pyramid = $\frac{1}{3}$ x base area x height

But,

base area = length x width

                 = 12 x 12

                 = 144 square feet

So that,

volume of the pyramid = $\frac{1}{3}$ x 144 x 7.1

                            = $\frac{1}{3}$ x 1022.4

                            = 340.8

The volume of the given pyramid is 340.8 cubic feet.

Answer 2

Answer:

340.8

Explanation:

The volume of an object is a consideration of the dimensions of the object with respect to 3 dimensions.

volume of a pyramid =  x base area x height

But,

base area = length x width

                = 12 x 12

                = 144 square feet

So that,

volume of the pyramid =  x 144 x 7.1

                           =  x 1022.4

                           = 340.8

The volume of the given pyramid is 340.8 cubic feet.
