Answer 1

Answer:

1350 cm^2

Step-by-step explanation:

Answer 2

Answer:  1350 square cm

===============================================

Explanation:

Each face of the cube is a square with side length 15. The area of the square is s^2 = 15^2 = 225. There are 6 faces, so 6*225 = 1350

------

In terms of a formula, the surface area of a cube is

SA = 6s^2

plugging in s = 15 gives

SA = 6*15^2

SA = 6*225

SA = 1350

Basically it's the same sort of steps as before.
