To find the volume \( V \) of a right rectangular prism, you can use the formula:
\[ V = l \cdot w \cdot h \]
where:
- \( l \) is the length,
- \( w \) is the width,
- \( h \) is the height.
Given:
- Length \( l = 1.5 , \text{m} \)
- Width \( w = 0.4 , \text{m} \)
- Height \( h = 3 , \text{m} \)
Now, substituting the values into the formula:
\[ V = 1.5 \cdot 0.4 \cdot 3 \]
First, calculate \( 1.5 \cdot 0.4 \):
\[ 1.5 \cdot 0.4 = 0.6 \]
Then multiply by height:
\[ 0.6 \cdot 3 = 1.8 \]
Thus, the volume \( V \) is:
\[ V = 1.8 , \text{m}^3 \]
The correct response is:
V = 1.8 m³
