Answer 1

Answer:

Given

LENGTH = 4m

BREDTH = 5m

HEIGHT =3m

DENSITY=1.29kg/ $m^{3}$

Volume of the room is given as V = L× B × H

                                                          = 5 × 3 × 4

                                                          = 60$m^{3}$

We know, Mass = Density×Volume.

NOW, MASS = 1.29 kg/$m^{3}$ x 60 m

                     =77. 4 kg

THEREFORE MASS IS 77.4 Kg
