Given:
The surface area of the cube is 13.5 cm2.
Find the area of one face of the cube. It is known that all the faces of the cube are equal to each other and that there are only six of them:
Sg = 13.5: 6 = 2.25 cm2.
We calculate the side of the cube, knowing that all the edges are equal in length to each other and are found by the formula a = √Sg:
a = √Sg = √2.25 = 1.5 centimeters.
Answer: The side of the cube is 1.5 centimeters.
