Question

A solid right pyramid has a square base with an edge length of x cm and a height of y cm. Which expression represents the volume of the pyramid? xy cm3 x2y cm3 xy2 cm3 x2y cm3

Answer 1

B

Explanation:

Answer 2

Thus, volume of pyramid =
`(1)/(3)x^2y` cm³

Explanation:

Given: A solid right pyramid has a square base with an edge length of x cm and a height of y cm.

We have to choose from the given options an expression for the volume of the pyramid.

Volume of pyramid =
`(1)/(3)* Area\ of\ base * height`

Since base is a square with edge length x cm.

Area of square = (side)² = x²

Thus, volume of pyramid =
`(1)/(3)x^2y` cm³
