Definition of a cubeA cube is a solid of six equal square sides.A cube is a box-shaped solid object that has six identical square faces. It is a solid that has six square faces of equal size that meet each other at right angles. The volume of a cube can be found by multiplying the edge length three times. To calculate the volume of a cube, identify the length of the side and multiply the length by itself three times. A cube has all its faces in a square shape. All the sides have equal dimensions. To go furtherThe cube has 6 square faces, 12 edges of the same length and 8 vertices.All the faces of the cube have the same dimensions. All faces of the cube are in a square shape. The angles in a cube are all right angles The edges opposite to each other are parallel. Cube or cuboidWhat is the difference between a cube and a cuboid ? The difference is that a cube has six square-shaped faces of the same size and a cuboid has rectangular faces.Differences between a cube and a cuboid: Faces: a cube and a cuboid have both six faces, all squares for a cube but all rectangles for a cuboid. Diagonals: a cube and a cuboid have both twelve diagonals on the surface, all equal for a cube, but for a cuboid in sets of four diagonals, each of three different lengths. A cube and a cuboid have both four internal diagonals, all equal for a cube, but for a cuboid in two pairs of different lengths. Is every cube a cuboid?Yes, all cubes are cuboids. A cuboid is a prism with 6 rectangular faces, and a cube is also a prism with 6 rectangular faces. Every cube is a cuboid. Indeed a cube is a special case of the cuboid, where all its dimensions such as length, breadth and height are equal. The cube is a special case of the square cuboid in which all six faces are squares. |
