Question

What is the volume of the pyramid ? 8ft 7ft 7ft

A. 56 ft
B. 130 2/3 ft
C. 196 ft
D. 392 ft

Answer 1

Volume of pyramid is:

`130(2)/(3)\ ft^3`

Explanation:

We know that the volume V of a pyramid is one-third the area of the base times the height h.

First we find the area of base let it be A.

A=7×7 ft²

A=49 ft²

Volume of pyramid=

`(1)/(3)* A* h`

Volume=

`(1)/(3)* 49* 8`

`= (392)/(3)\\ \\=130(2)/(3)\ ft^3`

Hence, Volume of pyramid is:

`130(2)/(3)\ ft^3`
