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

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

Substituting the given dimensions:

\[
\text{Volume} = 6\, \text{m} \times 3.5\, \text{m} \times 0.1\, \text{m} = 2.1\, \text{m}^3
\]

Therefore, you will need **2.1 cubic metres of concrete** for the floor.

Would you like further details or have any questions?

Here are 5 related questions:
1. What would be the volume if the depth was increased to 0.2m?
2. How much would the volume decrease if the width was reduced by 0.5m?
3. If the floor was 7m long instead of 6m, how much more concrete would be required?
4. How would you calculate the weight of concrete required given its density?
5. What would the cost be if concrete is priced per cubic meter?

**Tip:** Always check that the units (m, cm, etc.) are consistent when calculating volume.

Learn how to calculate the volume of concrete needed for a rectangular floor with dimensions 6m by 3.5m by 0.1m. This solution uses the formula for the volume of a rectangular prism and provides step-by-step guidance. Ideal for students in Grades 6-8.
