To find the volume of a rectangular prism, we need to use the formula:
[tex]\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \][/tex]
Here are the dimensions provided:
- Length: [tex]\( 4 \text{ ft} \)[/tex]
- Width: [tex]\( 12 \text{ ft} \)[/tex]
- Height: [tex]\( 6 \text{ ft} \)[/tex]
Substitute the given values into the formula:
[tex]\[ \text{Volume} = 4 \text{ ft} \times 12 \text{ ft} \times 6 \text{ ft} \][/tex]
This calculation yields:
[tex]\[ \text{Volume} = 288 \text{ ft}^3 \][/tex]
Therefore, the volume of the rectangular prism is:
[tex]\[ 288 \text{ ft}^3 \][/tex]
So, the correct answer is:
[tex]\[ \boxed{288 \text{ ft}^3} \][/tex]
