I don't think your son's teacher would expect him to answer the question using a conversion website.
The methodology for answering this question is fairly straight forward.
First, determine how many cubic centimetres in a cubic metre.
As there are 100 cms in a metre, there are 100 cubed cubic centimetres in a cubic metre: that is 1,000,000.
The mass of the medium is 7 grams per cubic centimetre so the mass of 1 cubic metre of the medium is 7 x 1,000,000 or 7 million grams.
Divide by 1 million to convert grams to tonnnes (1,000 grams in a kilogram and 1,000 kilograms in a tonne) and the answer is 7 tonnes.
