A block of wood is floating on water with its dimensions 50cm x 50 cm x 50 cm inside water.
Calculate the buoyant force acting on the block. Take g = 9.8N kg-1.
Volume of the block = 50cm x 50cm x 50cm = 125000cm3
Expressing volume in m3 => 0.125 m3
g = 9.8N kg-1 or 9.8m/s2
We know that buoyant force = V ρ g
0.125 x 1000 x 9.8 = 1225N
