Blank? how do i do it?

a piece of rubber, dimensions 150mm x 150mm x 2mm needs to be moulded (compressed). given that the density of the rubber mix is 1,25g cm-3, what is the correct amount of blank required?

how do i do this?

Answer:
volume required = 15 x 15 x 0.2 = 45 therefore 45*1.25 would give the weight of rubber required, which is 56.25g. Devide the weight of a blank into this and that will show how many you need.
