Glass table and Vase force

Question

A 4kg vase of flowers is placed directly in the middle of a glass table. The glass tabletop itself weighs 8kg. With what force do each of the four legs of the table push on the glass after the vase has been placed on top?

Answer 1

If the table is circular or a square, then by symmetry, each leg will have the same force = (8+4)/4 = 3 kg.
