Question

You are given a cube with a length of 2.5 cm a width of 2.5 cm and a heigh of 2.5 cm and its mass is 295 g what is the density

Answer 1

Density = mass/volume
Volume = length x width x height
Volume = 2.5 x 2.5 x 2.5 
             = 15.625 cm^3
Density = 295/15.625
             = 18.88 g/cm^3
