The surface area of 45414 is the area of 6 congruent square faces.

(1) Divide 45414 by 6 to find the area of one face.

The area of each square face is the square of the side length of the square (the edge length of the cube).

(2) Take the square root of the answer from (1) to find the answer to the problem.

(You should get a side length of 87 cm)
