From a cubical piece of wood of side 21 cm, a hemisphere is carved out in such a way that the diameter of the hemisphere is equal to the side of the cubical piece. Find the surface area and volume of the remining piece.

Answer

`6835.5 cm^(3)`

Explanation

Surface area of the remaining piece = total surface area of the cube - area of the top of the hemispherical part + curved surface area of the hemisphere.
Volume of the ramining piece
= volume of the cube - volume of the hemisphere.
