To find the volume of a right rectangular prism, you use the formula:
[tex]\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \][/tex]
Given the dimensions:
- Length ([tex]\( l \)[/tex]) = 18 inches
- Width ([tex]\( w \)[/tex]) = 4 inches
- Height ([tex]\( h \)[/tex]) = 10 inches
Substitute the given values into the formula:
[tex]\[ \text{Volume} = 18 \, \text{inches} \times 4 \, \text{inches} \times 10 \, \text{inches} \][/tex]
Perform the multiplications step by step:
1. Multiply the length and the width:
[tex]\[ 18 \times 4 = 72 \][/tex]
2. Multiply the result by the height:
[tex]\[ 72 \times 10 = 720 \][/tex]
So, the volume of the right rectangular prism is:
[tex]\[ 720 \, \text{cubic inches} \][/tex]
Therefore, the correct answer is:
[tex]\[ 720 \text{ in}^3 \][/tex]
