Question

The brass cube having density of 6.8 grams/cc weight 850 kgs ,then its dimensions is -

Answer 1

Density is mass by volume
I kg is 1000g
6.8 is 850000/volume
Volume is 8500000/68
Volume is 125000
Side is cube root of volume
50

Answer 2

density = 6.8g/cc
mass 850kg
density =mass/volume
6.8=850/a^3                 (VOLUME OF CUBE=a^3)
a^3=850/6.8
a^3=125cm
a=5cm                         (taking cube root both sides)
