5. A hemispherical depression is cut out from one face of a cubical wooden block such that the diameter of the hemisphere is equal to the edge of the cube. Determine the surface area of the remaining solid.
It is given to us that diameter of Hemisphere is equal to edge of cube
Radius of Hemisphere
Surface Area of Solid = Surface Area of 5 faces of cube + Inner Surface Area of Hemisphere + Blue Area on the Top Face ABCD
(Area of Square ABCD - Area of Inscribed Circle in square ABCD)
