Find the volume of a cuboid which is 15 m long, 12 m wide and `4.5 m` high.

Answer

To find the volume of a cuboid, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the dimensions of the cuboid:**
- Length (L) = 15 m
- Width (B) = 12 m
- Height (H) = 4.5 m

2. **Use the formula for the volume of a cuboid:**
- The formula for the volume (V) of a cuboid is given by:
\[ V = L \times B \times H \]

3. **Substitute the values into the formula:**
- Substitute the known values into the formula:
\[ V = 15 \, \text{m} \times 12 \, \text{m} \times 4.5 \, \text{m} \]

4. **Calculate the product of length and width:**
- First, calculate \(15 \times 12\):
\[ 15 \times 12 = 180 \, \text{m}^2 \]

5. **Multiply the result by the height:**
- Now, multiply \(180 \, \text{m}^2\) by \(4.5 \, \text{m}\):
\[ 180 \times 4.5 = 810 \, \text{m}^3 \]

6. **State the final answer:**
- Therefore, the volume of the cuboid is:
\[ V = 810 \, \text{m}^3 \]
