Weight of body =weight of liquid displaced by the body so,
W = 1000 * 9.81 * 2 * 3 * 0.6
W = 35.316KN.
W = 1000 * 9.81 * 2 * 3 * 0.6
W = 35.316KN.

Depth of immersion =0.6.
= sp. Grvty x depth of body.
Depth of body = 1m.
Therefore sp. gravty=0.6 hence density of body, ρ.
=600kg/m^3.
Wt of body =rho V g= 600x 3x2x1x9.81 = 35316N.
= sp. Grvty x depth of body.
Depth of body = 1m.
Therefore sp. gravty=0.6 hence density of body, ρ.
=600kg/m^3.
Wt of body =rho V g= 600x 3x2x1x9.81 = 35316N.

Weight of body = weight of water displaced = buoyancy force.
= Density x volume x g.
= 1000 x 3 x 2 x 0.6 x 9.81.
= 35316 N = 35.316 KN.
= Density x volume x g.
= 1000 x 3 x 2 x 0.6 x 9.81.
= 35316 N = 35.316 KN.

Press= density * sp.gra * depth.
Press = 1 * 9.81 * 0.6,
Press = 5.88 KN/m2.
Wt of body = press* area.
Wt. Of body= 5.88 * 6.
Ans= 35.5 Kn.

The weight of the body = (3*2*1) * 9.81*0.6.
= 35.3KN.
= 35.3KN.

Given,
Length 3M.
Whidth 2M.
Depth 1M and depth of immersion 0.6.
3x2x0.6 = 3.6M^3.
Weight of water 9.81x3.6 = 35.3KN.
Length 3M.
Whidth 2M.
Depth 1M and depth of immersion 0.6.
3x2x0.6 = 3.6M^3.
Weight of water 9.81x3.6 = 35.3KN.

Weight of water displaced(W)= density * Volume(V).
= (9.81) * (3 * 2 * 0.6),
= 9.81 * 3.6,
= 35.316 KN.
= (9.81) * (3 * 2 * 0.6),
= 9.81 * 3.6,
= 35.316 KN.
