Answer:
150cm²
Explanation:
cube has 6 sides of equal area.
each side is a square.
area of square = length X width (or length X height, width X height).
area of one side = 5 X 5 = 25cm².
6 sides, so total surface area = 6 X 25 = 150cm²
of the entire cube: 150
how you find the surface area of a cube is to find the area of just one side then timesing it by 6. so one square is 5 by 5. five times five is 25. then 25 times 6 is 150.
hope this helps :]
