well, since you're given v ery little info, you should expect the calculation to be relatively simple.

density is gm/cm^3. You are given two data: g of rock and cm^3 volume, so

density = 139.943g/29.7cm^3 = 4.712 g/cm^3

wrong the actual formula is d=m/v
so you take the mass and divide it by volume
which is D=M/V= 399.9g/22.7 that is =1.76g/cm3=centemeter cube
