To find the volume of a rectangular prism, you can use the formula:
\[ V = \text{height} \times \text{width} \times \text{length} \]
In this case, the dimensions of the rectangular prism are:
- Height = 5 feet
- Width = 20 feet
- Length = 5 feet
Plugging in the values:
\[ V = 5 , \text{feet} \times 20 , \text{feet} \times 5 , \text{feet} \]
Calculating this:
\[ V = 5 \times 20 = 100 \] \[ V = 100 \times 5 = 500 \]
Thus, the volume \( V \) is:
\[ V = 500 , \text{cubic feet} \]
So the volume of the rectangular prism is \( 500 , \text{feet}^3 \).
