length in cm of one side of perfect cube of gold with a density of 18g/cc and mass of 25g?
How would i set up this equation? I don't know what length formula I would use, because I know that i am not supposed to just divide the density by the mass, because that would be incorrect. Maybe the length would be 1/4x = Mass x Density??

  1. mass = volume x density
    25g = volume x 18 g/cc
    Solve for volume in cc (cubic centimeters) = 1.389 cc.
    Volume of a cube = length^3
    1.389cc = length^3
    So take the cube root of both sides to find
    length = cube root(1.389) = 1.1157 cm which rounds to 1.1cm to two significant figures.
