a rectangular block of size 4m.3m.2m is placed on the ground on its largest face calculate the work done when the block is placed on its smallest face given the density of the material of the block to be 10kg/m^3

Work is done when the force acting on a body produces a displacement of the body.
The block is placed on one of its face. It does not move from that place.
 
Thus, the work done when the block is placed on its smallest face is zero.

During calculation of acceleration due to gravity above the surface of earth if we assume that there is an external force opposite to that of Earth's gravity then the cos angle will be 180 between the two forces which is negative(-1), if we put the value in the equation of dw = F.dx then the final value of potential energy is positive which is not possible.how and why??
