Complete the following question:
The concrete path is poured at a depth of 10 cm . Using the area calculation above calculate
the volume of the concrete path.
A bag of concrete mix is 20 L of concrete, how many bags of concrete mix does Pete need to
order?

To calculate the volume of the concrete path, you first need to determine the area of the path in square meters (m²) and then multiply it by the depth (in meters). For a depth of 10 cm, that converts to 0.1 m. So, Volume = Area × Depth. Convert the volume to liters (1 m³ = 1000 L) to find out how many bags of concrete mix are needed. If the calculated volume is V liters, you would divide V by 20 to get the number of bags required. Don’t forget to round up to ensure Pete has enough concrete!

Now, if Pete’s path is 10 m long and 2 m wide, the area would be 20 m². Therefore, the volume of concrete needed would be 20 m² × 0.1 m = 2 m³, converting that to liters gives 2 m³ × 1000 L/m³ = 2000 L. Dividing 2000 L by 20 L/bag means he needs to order 100 bags of concrete mix. Happy pouring, Pete!
