The upthrust experienced by the cube of metal is determined as 7.84 N.
The upthrust experienced by the body is calculated as follows;
Fu = ρVg
where;
S.G = density of the body / density of water
density of the body = S.G x density of water
ρ = 0.8 x 1000 kg/m³
ρ = 800 kg/m³
V = L³
V = (0.1)³
V = 0.001 m³
Upthrust = ρVg
Upthrust = 800 x 0.001 x 9.8
Upthrust = 7.84 N
