Volume and Surface Area Of Cube

In geometry, a cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. The cube can also be called a regular hexahedron and is one of the five Platonic solids. It is a special kind of square prism, of rectangular parallelepiped and of trigonal trapezohedron. The cube is dual to the octahedron. It has cubical symmetry (also called octahedral symmetry). It is special by being a cuboid and a rhombohedron.

A cube is a solid shape that has :

• 6 square faces all equal in size.
• 8 vertices ( corners) and
• 12 equal edges

Surface Area of Cube :
6b2 or 6 x b2

Volume of the cube
Volume= b3  or b x b x b
              = 10 x 10 x 10
              = 100 x 10
              = 1.000 cm3

Example
A cube has 12 cm ribs. Calculate the surface area and volume of ​​a cube !
Surface area = 6b2 
                       = 6 x 12 x 12
                       = 72 x 12
                       = 864 cm
Volume = b x b x b
              = 12 x 12 x 12
              = 144 x 12
              = 1.728 cm
