* Tonnes are a unit of weight (mass).
* 72 and 38 are likely just numbers. They don't inherently represent anything that could be measured in tonnes.
To get an answer in tonnes, you need to know what 72 and 38 represent. For example:
* If 72 represents kilograms and 38 represents the number of bags: 72 x 38 would give you the total weight in kilograms, which you could then convert to tonnes.
* If 72 represents the volume in cubic meters and 38 represents the density in tonnes per cubic meter: 72 x 38 would directly give you the total weight in tonnes.
Please provide more context about what 72 and 38 represent so we can help you find the answer in tonnes.
