    To find the surface area of the whole cube, you need to first find the area of one side.

    So one side is just a square with length and width of 7mm. So the area would be 7 x 7 = 49mm².

    Since there are 6 sides on a cube, multiply this area by 6 to give you the whole surface area of the cube.

    49 x 6 = 294mm²
