To find the volume of a rectangular prism, you can use the formula:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]
Given the dimensions of the rectangular prism are:
- Length = 2.5 feet
- Width = 3.5 feet
- Height = 4 feet
Substituting the values into the formula:
\[ \text{Volume} = 2.5 , \text{feet} \times 3.5 , \text{feet} \times 4 , \text{feet} \]
First, calculate \(2.5 \times 3.5\):
\[ 2.5 \times 3.5 = 8.75 \]
Next, multiply the result by 4:
\[ 8.75 \times 4 = 35 \]
Thus, the volume of the rectangular prism is:
\[ \text{Volume} = 35 , \text{cubic feet} \]
Therefore, the volume of the rectangular prism is 35 cubic feet.
