Question

The volume of the figure is 9ft 15ft 15ft 15ft please help fast PLEASE!

Answer 1

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)`.
