Know about Cube:

I have covered almost all the shapes of geometry but geometry itself is vast concept. There are more shapes to explore, and today we will try to know the cube better.

A cube is a region of space formed by six identical square faces joined along their edges. Three edges join at each corner to form a vertex. The cube can also be called a regular hexahedron.

Let us know about that how to find the volume of a cube. The volume of a cube is found by multiplying the length of any edge by itself twice. For example if the length of an edge is 4, the volume is 5 x 5 x 5 = 125
OR
Using the volume of a cube formula: Volume = S3.

Parts of a cube:
Face: Also called as facet or sides.
Edge: A line segment formed where two edges meet. A cube has 12 edges.
Vertex: A point formed where edges meet. A cube has 8 vertices.
Face diagonals: Face diagonals are line segment linking the opposite corners of a face.
Space diagonals: Space diagonals are line segments linking the opposite corners of a cube, cutting through its interior.
