A 0.0979-m x 0.215-m x 0.260-m block is suspended from a wire and is completely under water. What buoyant force acts on the block?

Would I multiply all the numbers?

1 answer

Yes, for the volume of the block, but you also have to multiply by the weight density of the fluid, which is
1000 kg/m^3 * 9.8 m/s^2 = 9800 N/m^3

Your answer must be in newtons, not cubic meters
