Answer» Step-by-step explanation: A cube is a solid BOX whose every surface is a square of same area. Take an empty box with open top in the shape of a cube whose each edge is 2 cm. Now fit cubes of EDGES 1 cm in it. From the figure it is clear that 8 such cubes will fit in it. So the volume of the box will be equal to the volume of 8 unit cubes together. Therefore, the volume of the cube = 8 cu cm Note that 8 = 2 × 2 × 2 Thus, volume of a cube = SIDE × side × side = side3 Hence, a cube has: (i) six SURFACES or faces, (ii) 8 vertices, (iii) 12 edges or sides of equal length. Cube Since a cube has all sides equal. Volume of a cube = (side × side × side) cubic units. = 1 × 1 × 1 cubic units Since area = side × side Volume of a cube = (area × side) cubic units.
