Explanation:
Density of cube, Db = 3.5g/cm³
Volume = side³
= (7)³ = 343cm³
Mass = Volume × Density
= 3.5 × 343
= 1200.5g
Density of water, Dw = 1g/cm³
Apparent weight can be calculated by the formula,
App. W / Act. W = 1 - Dw/Db
App.W / 1200.5 = 1 - 1/3.5
App.W / 1200.5 = 25/35
App.W = 25/35 × 1200.5
= 857.5g
In kg,
App.W = 0.8575kg
In N,
App.W = 8.575N
Therefore,
Apparent weight is less than 12.005N
