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, 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 the values into the formula:

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

You will need 2.1 cubic metres of concrete.

Here are 5 related questions:
1. What is the cost of concrete per cubic metre in your area?
2. How much does the weight of the concrete affect transport and handling?
3. What additional materials are needed when laying a concrete floor (e.g., mesh, reinforcement)?
4. How much time does concrete need to cure after pouring?
5. How do temperature and weather conditions affect the concrete setting process?

**Tip:** Always ensure the ground is well-prepared (leveled and compacted) before pouring the concrete for a stable foundation.

Learn how to calculate the volume of concrete needed for a floor with dimensions 6m (length), 3.5m (width), and 0.1m (depth). This problem demonstrates the use of the volume formula for a rectangular prism and is suitable for students in Grades 6-8.
