the volume of the wooden block= l×b×h

=2m×0.25m×0.10m

=0.05m^3

relative density = density of the object/density of water

0.6=density of the object/1000kg/m^3

density of the object=0.6×1000

=600kg/m^3

density of the object= mass/ volume

600kg/m^3=mass/0.5m^3

mass= 600kg/m^3×0.05m^3

mass=30kg

Answer:

  • pls mark as brainliest friend

Explanation:

Volume = l × h × w

= 2 × 0.5× 0.25 cm cube

= 0.25cm cube

Mass = Volume × Density

=0.25× 7.8

= 1950 g = 1.95 kg
