Question

A cuboidal metal block of dimensions 2m * 1m * 1m
weight 400 kg . Find the weight of a block of the same metal of size 1m * 1/2m * 1/2m.​

Answer 1

density remains the same

and

density is mass/volume

so

density of cuboidal block will be

400/2

i.e 200kg/m3

so weight of the block made by same metal will be

200*1*1/2*1/2

=50kg

so the weight if the block will be 50kg
