the formula for getting the density of an object is density = mass/volume = ρ = m/v
mass =42 kg volume = 22m3 we will work on the equation directly because they are already in there SI units density = 42 kg/22m3 density = 1.9090909090909 which if rounded can become 1.9 kg/m3 ans = the object's density is 1.9090909090909 kg/m3 or 1.9 kg/m3
