A block of wood is floating on water with it’s dimensions 50 cm × 50 cm × 50 cm inside water. Calculate the buoyant force acting on the block. Take g = 9.8 N kg^-1.

g = 9.8 N kg^-1

density of water = 1000 kg m³

dimensions of wooden block = 50 cm × 50 cm × 50 cm

= 0.5 m × 0.5 m × 0.5 m    [converting to metres]

Volume of wooden block = 0.5 m × 0.5 m × 0.5 m

= 0.125 m³

Buoyant force = volume of block × density of water × g

= 0.125 × 1000 × 9.8

= 1225 N
