A railway car is shaped like a rectangular prism with a length of 18 meters, a width of 3 meters, and a height of 4 meters.

Question

What is the volume of the railway car?

Enter your answer in the box.

Answer 1

The volume \( V \) of a rectangular prism can be calculated using the formula:

\[ V = \text{length} \times \text{width} \times \text{height} \]

Given:

• Length = 18 meters
• Width = 3 meters
• Height = 4 meters

Now, substituting the values into the formula:

\[ V = 18 , \text{m} \times 3 , \text{m} \times 4 , \text{m} \]

Calculating step-by-step:

1. \( 18 \times 3 = 54 \)
2. \( 54 \times 4 = 216 \)

Thus, the volume of the railway car is:

\[ V = 216 , \text{cubic meters} \]

So, the answer is \( \boxed{216} \).
