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 determine how many cubic meters of concrete are needed for the floor, you can use the formula for the volume of a rectangular prism:

\[
\text{Volume} = l \times w \times d
\]

where:
- \( l = 6 \) m (length)
- \( w = 3.5 \) m (width)
- \( d = 0.1 \) m (depth)

Substituting the given values:

\[
\text{Volume} = 6 \times 3.5 \times 0.1
\]

Calculating the volume:

\[
\text{Volume} = 2.1 \, \text{m}^3
\]

Therefore, you need **2.1 cubic meters** of concrete.

Would you like further details on the calculation or have any questions? Here are some related queries:

2. What is the weight of 2.1 cubic meters of concrete?
3. How much does concrete cost per cubic meter?
4. What are the steps to prepare the ground before pouring concrete?
5. How to estimate the curing time for the concrete?

**Tip:** Always order a little more concrete than calculated (about 10% extra) to account for spillage or uneven surfaces.
