Question

formula of volume of cube

Answer 1

Formula of volume of cube =
${a}^{3} \: or \: \: {side}^{3}$

Answer 2

Cube:A three-dimensioned solid cuboid whose length,breadth and height are all equal is called a cube. 




Cube is  combination of vertex,Edge,Faces Vertex: is point , where two or more lines meet(8).Edges: Edges is the line of the cube (12).Faces:the views of the object is called as Faces (6).



Volume:
The amount of space occupied by a three dimensional object is called as volume. volume of room is greater than volume of an match box. cubic unit are used to measure the volume of solid objects. 
Volume of cube:Measurement of volume is carried in cubic units whereas the area of region or surface s are measured in square units.
How to find the volume of cube/derivation
By measuring one side of the cube and cubing the length of the one side gives the volume.                                     (or)

Multiplying the length,width and the height of the cube gives the volume of cube.                                 V = l*h*wIn general volume of cube is side*side*side. Thus                                V = l*l*l                                   = l3
