Question

If I need to make a mold with a square base with a volume of exactly 28 cubic centimeters how many possible molds could I make?

Answer 1

infinite number even if no curvy tops

If it is rectangular then
x^2 h = 28
h = 28/x^2

Answer 2

if you want integer dimensions, then since

28 = 2^2 x 7
the mold must be 2x2x7 or 1x1x28

Answer 3

The original question is to make molds for candles. 1x1X28 (height), 1x28X1 (height), 1x2x14(height), 1x14x2(height), 2x14x1(height), 1x4x7(height), 1x7x4(height), 7x4x1(height), 2x2x7(height), 2x7x2(height), totally 10 molds.
