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

Which expression represents the volume of the pyramid?

One-thirdxy cm3
One-thirdx2y cm3
One-halfxy2 cm3
One-halfx2y cm3

Answer 1

Volume = (1/3) × (base area) × (height). Base area = x^2, height = y, so volume = (1/3)x^2y cm^3.

Answer: One-third x^2 y cm^3.
