## Homework Statement

A cube made from iron has sides equal to 20cm/side. The density of iron is 7860kg/m^3. The cube is completely submerged in water; the density of water is 1000kg/m^3. What is the buoancy force acting on the cube.

## Homework Equations

W(DL)= (D(L))(V)(g)

## The Attempt at a Solution

W(DL)=(1000kg/m^3)(8000cm^3)(10m/s^2) =8x10^7 Neutons

Im not sure if this answer is correct ????
