The surface area of a cube can be calculated by finding the area of each of the cube's six square faces and adding them together. Since all sides of a cube are equal, the area of one face is the side length squared. Therefore, the surface area of a cube with a side length of 8mm is 6 times 8mm squared, which equals 384 square millimeters.
6 faces, each of 8mm*8mm = 6*64mm2 = 384 mm2
It is: 886 = 384 square mm
A hexagon has 6 sides of equal length. The perimeter of a hexagon with a side length of 8mm = 6 x 8mm = 48mm.
