You need to put in a concrete floor. The floor dimensions are: Length (l) 6m, Width (w) 3.5m, Depth (d) 0.1m. How many cubic metres of concrete do you need?

To calculate the volume of concrete needed, you use the formula for the volume of a rectangular prism:

\[
V = l \times w \times d
\]

Where:
- \( l = 6 \, \text{m} \) (length),
- \( w = 3.5 \, \text{m} \) (width),
- \( d = 0.1 \, \text{m} \) (depth).

Substituting the values into the formula:

\[
V = 6 \times 3.5 \times 0.1 = 2.1 \, \text{cubic meters}
\]

So, you will need **2.1 cubic meters** of concrete.

2. How much does the depth of the floor affect the total concrete required?
3. What is the difference between cubic meters and square meters in measurements?
4. How do you determine the right mix of concrete for different projects?
5. How does temperature affect the setting time of concrete?

**Tip**: Always order a bit more concrete than calculated to account for spillage and imperfections in the surface.
