How do you find the surface area of cube???

(a is the length of the side of each edge of the cube)

In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a 2 . Since these are all the same, you can multiply one of them by six, so the surface area of a cube is 6 times one of the sides squared.

Example #1:

Find the surface area if the length of one side is 3 cm

Surface area = 6 × a² 

Surface area = 6 × 3² 

Surface area = 6 × 3 × 3 

Surface area = 54 cm² 

Surface Area of a Cube = 6 a 2

Length*width*6=SA=ans

Thank you guys for the answers to my question.
