To calculate the volume \( V \) of a rectangular prism, you use the formula:
\[ V = \text{height} \times \text{width} \times \text{length} \]
Given the dimensions:
- Height = 4 m
- Width = 10 m
- Length = 18 m
Substituting the values into the formula:
\[ V = 4 , \text{m} \times 10 , \text{m} \times 18 , \text{m} \]
Calculating step-by-step:
- Calculate \( 4 \times 10 = 40 , \text{m}^2 \)
- Now multiply by the length: \( 40 \times 18 = 720 , \text{m}^3 \)
Thus, the volume of the rectangular prism is
\[ \boxed{720 , \text{m}^3} \]
