The surface area of a cube with the diagonal of a square equal to 270000
where a is the side of the cube
A cube (or hexahedron) is a regular polyhedron that consists of polygons that are squares.
Cube surface area formula 
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 = 3d2
= 3·3002
= 3·90000
=
270000
a: The surface area of a cube with the diagonal of a square equal to 270000
