a block of wood 3 cm on each side has a mass of 27 g. What is the density of the block
Density = mass / volume.
First you need to find the volume of the cube block, which is V = s3.
v = (3)3 = 27
density = 27cm/27g
density = 1
A slight correction (same answer)
Density = mass / volume (not volume/mass)
volume = 27 cm^3 Mass = 27 g density = 27 g / 27 cm^3 = 1 gm/cm^3 (MUST include units to be correct)
