How would I go about doing this problem?

specific gravity is density of an object relative to water.

ok 1st you need to find the density of the unknown material

volume = 2^3 = 8cm^3

mass = .2kg = 200g

density = mass/volume

200/8 = 25 g/cm^3 <---density of unknown material.

So specific gravity of the unknown is (25 g/cm^3)/(1g/cm^3) = 25.

Just remember your units have to cancel out. specific gravity has no dimensions.

Did you see this in a practice test or study book? I haven't run into anything like this.

And hopefully we never will!

It is in kaplans subject test.

are there questions about gravity on the real test?

I highly doubt it. gravity would pertain more to physics and we're not tested on physics.
