I have one that I am actually really struggling with. Here it is...

A block of stone has a mass of T tonnes. The density of the stone is 2.5g/cm^3. Show that the volume of the block is 0.4Tm^3.

Erm that question seems kinda easy idk if I'm doing it wrong though, I done 70-15=55 then 55+120 gave me 175. The assumption I made is that none of the tags fell off.

(70/15)*120 = 560


That's correct :smile: but would have been better if you let them work it out themselves.
