Question

a peice of brass of volume 30cm cube has a mass of 252g.find the density of brass in gcmcube and kg minus cube

Answer 1

given,

volume= 30 cm(we change it into m)=30/(100*100*100) =0.00003m cube

mass= 252gm(we also change into kg)=252/1000=0.252

now using the formula of density we get

density=mass/vol

d=0.252/0.00003

d=8400

we we get the density 8400kg/m^3
