Answer: Volume = 1/3(x³ + 2x²)
Explanation:
The formula for determining the volume of a right pyramid with a square base is expressed as
Volume = 1/3 × base area × height
From the information given,
base length = x inches
Base area = x²
The height is two inches longer than the length of the base. It means that the height is (x + 2) inches.
Therefore, the expression represents the volume in terms of x is
Volume = 1/3 × x²(x + 2)
Volume = 1/3(x³ + 2x²)
