Math CentralQuandaries & Queries


I have to transport gravel in a 7 ton lorry and I know how many cubic meters of gravel I need, but I need to know how many cubic meters of gravel a 7 ton lorry can hold.
Thanks, Jackie

Hi Jackie,

It depends on the type of gravel you are transporting. On the SImetric site they list the densities of dry materials and they have densities in Kilograms per cubic meter for 4 types of gravel.

First you need to convert 7 tons to kilograms. I asked Google. I typed 7 tons in kilograms into Google and received 7 short tons = 6 350.29318 kilograms. Divide this number by the density of the gravel from the SImetric site to obtain the volume in cubic meters.

I hope this helps,
