Question

A hemispherical depression is cut from one face of a cubical wooden block such that the diameter " L "of the the hemisphere is equal to the edge of the cube . Determine the surface area of the remaining solid?

Answer 1

HEYA MATE,

HERE IS UR ANSWER.

Surface area of the cubical wooden box = 6(edge)2
Let the edge of a cube = l

∴ Surface area of a cube = 6(l)2

Diameter of a hemisphere = l

Radius of a hemisphere = l/2

=> Surface area of a hemisphere = 2p r2

Surface area of the remaining solid = Surface area of a cube - Surface area of a hemisphere

I HOPE IT HELPS U.
