Question

A right pyramid with a square base has a base length of x inches, and the height is two inches longer than the length of the base. Which expression represents the volume in terms of x?
StartFraction x squared (x + 2) Over 3 EndFraction cubic inches
StartFraction x (x + 2) Over 3 EndFraction cubic inches
StartFraction x cubed Over 3 EndFraction + 2 cubic inches
StartFraction x cubed + 2 Over 3 EndFraction cubic inches

Answer 1

Answer:

The answer to your question is Volume = (1/3)(x²)(x + 2)

Step-by-step explanation:

Data

length = x

height = x + 2

Volume = ?

Formula

Volume = 1/3Ab h

Process

1.- Calculate Ab

Ab = length x length

-Substitution

     = (x)(x)

-Simplification

     = x²

2.- Substitution

Volume = (1/3)(x²)(x + 2) or (1/3)(x³ + 2x²)
