Calculate the amount of concrete needed for pouring footings using metric measurements.
length * width * depth = Volume
footings length = 200 m width = 600 mm footings depth = 100 mm
To be able to do a straight calculation, the units you use have to be the same and when you are using metric units, that is a simple step.Change the millimetres to metres by dividing by 1000 (one metre = 1000 millimetres)
600 ÷ 1000 = 0.600 metres 100 ÷ 1000 = 0.100 metresNow using the above formula, you can easily calculate the volume of the footings in cubic meters;
200 * 0.6 * 0.1 = 12You need 12 cubic metres of concrete.
