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) .
