To find the volume of a rectangular prism (in this case, the swimming pool), you can use the formula:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{depth} \]
In this case, the dimensions of the pool are:
- Length = 12 feet
- Width = 9 feet
- Depth = 7 feet
Now, substituting in the values:
\[ \text{Volume} = 12 , \text{feet} \times 9 , \text{feet} \times 7 , \text{feet} \]
Calculating step by step:
-
Multiply the length and width: \[ 12 \times 9 = 108 , \text{square feet} \]
-
Now, multiply that result by the depth: \[ 108 \times 7 = 756 , \text{cubic feet} \]
So, the volume of the pool is 756 cubic feet.
The correct response is: 756 cubic feet.
