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?

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.
