Question

Keysha needs to fill a container with cement. The container is in the shape of a right rectangular prism. The container has a length of 7.5 feet, a width of 5 feet, and a height of 3 feet. What is the volume of the container?

(1 point)

1,125 ft.3

37.5 ft.3

15.5 ft.3

112.5 ft.3

Answer 1

To find the volume of a right rectangular prism, you can use the formula:

\[
\text{Volume} = \text{length} \times \text{width} \times \text{height}
\]

Given the dimensions of the container:
- Length = 7.5 feet
- Width = 5 feet
- Height = 3 feet

Now, plug in the values into the formula:

\[
\text{Volume} = 7.5 \, \text{ft} \times 5 \, \text{ft} \times 3 \, \text{ft}
\]

Calculating this step-by-step:

1. \( 7.5 \times 5 = 37.5 \)
2. \( 37.5 \times 3 = 112.5 \)

Therefore, the volume of the container is:

\[
\text{Volume} = 112.5 \, \text{ft}^3
\]

The correct answer is **112.5 ft³**.
