To find the volume of a rectangular prism, we use the formula:
[tex]\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \][/tex]
Given the dimensions:
- Length = 18 inches
- Width = 12 inches
- Height = 6 inches
Substitute these values into the formula:
[tex]\[ \text{Volume} = 18 \, \text{in.} \times 12 \, \text{in.} \times 6 \, \text{in.} \][/tex]
Multiplying these together:
[tex]\[ \text{Volume} = 18 \times 12 \times 6 \][/tex]
This calculation results in:
[tex]\[ \text{Volume} = 1296 \, \text{in.}^3 \][/tex]
Therefore, the volume of the rectangular prism is:
[tex]\[ 1296 \, \text{in.}^3 \][/tex]
So, the correct answer is:
[tex]\[ \boxed{1296 \, \text{in.}^3} \][/tex]
