To find the volume \( V \) of a rectangular prism, you can use the formula:
\[ V = \text{length} \times \text{width} \times \text{height} \]
Given the dimensions:
- Length = 9 cm
- Width = 18 cm
- Height = 15 cm
Now, substitute these values into the formula:
\[ V = 9 , \text{cm} \times 18 , \text{cm} \times 15 , \text{cm} \]
First, calculate \( 9 \times 18 \):
\[ 9 \times 18 = 162 , \text{cm}^2 \]
Next, multiply by the height:
\[ 162 , \text{cm}^2 \times 15 , \text{cm} = 2430 , \text{cm}^3 \]
Thus, the volume of the rectangular prism is:
\[ \boxed{2430 , \text{cm}^3} \]
