What volume of lead (of density 11.3 g/cm3) has the same mass as 304 cm3 of a piece of redwood (of density 0.38 g/cm3?(Answer in units of cm3.

Okay, so this is like testing us over the basics, but I really can't get the answer! I tried everything...

Do you have an answer?

mass redwood = volume x density = 304*0.38 = ?? grams.

volume Pb = mass/density

volume Pb = ??g redwood/density Pb.
