cubic metres into area

Postby angela » Sun Feb 19, 2006 6:29 pm

If I am allowed to spread soil 1 metre deep but only allowed 2500 cubic metres very roughly what amount of area would that cover, or how do I work out cubic metres into sq metres, I'm stuck also is a cubic metre roughly a tonne hope someone can help thanks

The area it will cover is exactly 2500 square meters (if nothing changes in the soil dynamics).

If you have 2500 cubic meters, you have 2500 separate units that measure 1 meter long x 1 meter wide x 1 meter tall.

2500 cubic meters / 1 meter high = 2500 square meters.

If you take the square root of 2500 square meters, you will have one side of the area it will cover, which is 50 meters. 50 meters x 50 meters = 2500 square meters with soil 1 meter deep.

You want it 0.5 meters thick? 2500 cubic meters / 0.5 meter = 5000 square meters. The square root of 5000 is 70.71 meters, so the area covered will be 70.71 meters long x 70.71 meters wide x 0.5 meters high.

A cubic meter is a volume, a tonne is a unit of mass. Although a cubic meter of something may weigh a tonne, the units aren't synonymous.
