To calculate the volume \( V \) of a rectangular prism, you can use the formula:
\[ V = \text{height} \times \text{width} \times \text{length} \]
Given:
- Height = 3 cm
- Width = 2 cm
- Length = 18 cm
Now, plug in the values:
\[ V = 3 , \text{cm} \times 2 , \text{cm} \times 18 , \text{cm} \]
Calculating this step by step:
- \( 3 \times 2 = 6 \)
- \( 6 \times 18 = 108 \)
So,
\[ V = 108 , \text{cm}^3 \]
Therefore, the volume of the rectangular prism is \( 108 , \text{cm}^3 \).
