surface area is the area of a face and add all faces areas up cubes have square faces
since it is a cube the areas of the face are the same and there are 6 faces so 100/6= 16.67
the area of a square is l times w and l and w are same since it is a square do the square root of 16.67 and the only answer that has the square root of 16 is 4.1
