Question

A Block of Glass is 60 cm long ,0.25 m wide and has a thickness of 4 cm.Find the density if its mass is 30 kg​

Answer 1

Answer:

5×10^-3 kg/m^3

Explanation:

GIVEN,

length=60cm

breadth=0.25m =0.25×100=25 cm

thickness=4cm

mass= 30kg

solution:

density= mass÷volume

volume= length×breadth×height

so, volume=60×25×4=6000 cm^3 = 6×10^-3 m^3

density=30kg/6×10^-3 m^3

=5×10^-3 kg/m^3
