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
