Numeracy question. 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?
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 for the floor, you can use the formula for the volume of a rectangular prism:

\[
\text{Volume} = \text{Length} \times \text{Width} \times \text{Depth}
\]

Given:
- Length ($l$) = 6 m
- Width ($w$) = 3.5 m
- Depth ($d$) = 0.1 m

Substitute these values into the formula:

\[
\text{Volume} = 6 \times 3.5 \times 0.1 = 2.1 \, \text{cubic metres}
\]

You will need **2.1 cubic metres** of concrete for the floor.

Would you like more details on the calculation, or do you have any questions?

Here are 5 related questions:
1. How would the volume change if the depth increased to 0.15 m?
2. What is the cost of the concrete if it's priced at $100 per cubic metre?
3. How many square metres of the floor does this calculation cover?
4. How would you calculate the concrete needed for a sloped floor?
5. What additional factors might you need to consider in real-world concrete work?

**Tip:** When working with construction materials, it's always a good idea to order slightly more than the calculated amount to account for spillage or error.
