A cube or a regular hexahedron (hexa means six) is a closed space having six identical square faces joined along their edges. Three edges join at each corner to form a vertex.

Structure of a Cube

Sides | A cube has 6 sides or faces which are all squares |
Edge | A cube has 12 equal length edges. |
Vertex | A cube has 8 vertices or points where 3 edges meet. |
Face Diagonal | Each face of a cube has two diagonals. Thus, a cube has a total of 12 face diagonals. |
Space Diagonal | Space diagonals are line segments linking the opposite corners of a cube. A cube has 4 space diagonals. |
Cube Surface Area Formula
The surface area of a cube is the sum of areas of all the faces of the cube, that covers it. The formula for the surface area of a cube is equal to six times of square of the length of the sides of the cube.
Surface area of cube= 6s2 Square Unit where s represents a side of the cube
Cube Volume Formula
A cube has all edges the same length. Therefore, the volume of a cube is determined by multiplying the length of any edge three times i.e SxSxS where s is the length of the edge. Or as a formula: volume = S3
Cube Face Diagonal Formula
The line segments linking the opposite corners of a faceis called face diagonals. There are 12 face diagonals in a cube.The length of the face diagonals is given by the formula face diagonal=√2S2
Cube Surface Diagonal Formula
The line segments linking the opposite corners of a cube,passing through its interior. A cube has 4 space diagonals. The formula for length space diagonal=√3S2 where s is the length of one side (edge).
