Cube surface area with side 60 equal to 21600
A cube (or hexahedron) is a regular polyhedron that consists of polygons that are squares.
Cube surface area formula 
where a is the side of the cube
where d is the diagonal of the square
where D is the diagonal of the cube
where Sh is the area of the inscribed ball
where V is the volume of the cubeSolution:
S = 6a2
= 6·602
= 6·3600
=
21600
a: Cube surface area with side 60 equal to 21600
