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 amount of concrete needed, we can use the formula for the volume of a rectangular prism (which applies to the floor):

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

Substitute the given values:

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

Now, let's calculate:

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

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