1) $13.5 cm^2$ 2) The Area of each face is the length of one edge squared. 3) The Surface Area of a cube is the sum of all the areas of the faces.

1) To find the surface area, the following formula is used: $6s^{2}$ Using 1.5 as the side length, the surface area would be $A= 6(1.5^2)$ $A = 6(2.25)$ $A = 13.5 cm^2$
