Explanation:

Formulas.

Square:
V = L * W * H

Square Pyramid:
V = \frac13b^2h

b = base.

Let's work on the square first.

Substitute the Length, Width, and Height of the square into the formula:


V=15 *15*15

Solve:


V=15^(3) =3,375

Let's work on the square pyramid.

Substitute 225 into the formula, and 9 (height):


V=(1)/(3)(15)^2(9)

Solve:


V=(1)/(3)225(9)


V=(1)/(3)(2025)


V=675

Add each volume:


3,375+675=4,050 ft^(3)

The total volume of the figure is
4,050 ft^(3).
