This is the concept volume and mass of solid materials. We are required to calculate the weight of the oil in the can, this will be given by:
weight=[volume of the can]*[mass per cubic centimeter (density)]
volume of the can is:
volume=πr^2h
radius,r=6 cm
height,h=10 cm
volume=π×6^2*10
volume=1,130.97 cm^3
thus the weight of the can will be:
weight=0.857×1,130.97
=969.244 grams
