To find the volume of a rectangular prism, you can use the formula:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]
Given the dimensions of the rectangular prism:
- Length = 5 cm
- Width = 9 cm
- Height = 4 cm
Now, substitute these values into the formula:
\[ \text{Volume} = 5 , \text{cm} \times 9 , \text{cm} \times 4 , \text{cm} \]
First, calculate \( 5 \times 9 \):
\[ 5 \times 9 = 45 \]
Next, multiply this result by 4:
\[ 45 \times 4 = 180 \]
So, the volume of the rectangular prism is:
\[ \text{Volume} = 180 , \text{cm}^3 \]
Thus, the final answer is:
\[ \text{Volume} = 180 , \text{cm}^3 \]
