Homework Statement


Calculate the buoyant force on a solid object made of copper and having a volume of 0.2 m^3 if it is submerged in water.

Homework Equations


B = pVg

The Attempt at a Solution


I followed the above equation and did
B = (8.92 x 10^3 kg/m^3)(0.2 m^3)(9.8 m/s^2)
B = 1.74 x 10^4
The correct answer is 1.96 x 10^3

I'm not sure it's just part of the formula. p = density

A density, sure, but not the one of copper.
