To calculate the volume of a right rectangular prism, you can use the formula:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]
In this case, the dimensions provided are:
- Length = 5 feet
- Width = 2.5 feet
- Height = 3.5 feet
Now, substitute the values into the formula:
\[ \text{Volume} = 5 , \text{ft} \times 2.5 , \text{ft} \times 3.5 , \text{ft} \]
Calculating step-by-step:
-
First calculate \(5 \times 2.5\): \[ 5 \times 2.5 = 12.5 \]
-
Then calculate \(12.5 \times 3.5\): \[ 12.5 \times 3.5 = 43.75 \]
So, the volume of the prism is:
\[ 43.75 , \text{ft}^3 \]
Therefore, the correct response is:
43.75 ft.³ (43.75 ft cubed).
