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 for the floor, we use the formula for the volume of a rectangular prism:

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

Given:
- Length (\(l\)) = 6 meters
- Width (\(w\)) = 3.5 meters
- Depth (\(d\)) = 0.1 meters

Substitute these values into the formula:

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

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