Answer 1

${\huge {\mathfrak {Answer :-}}}$

Let, the edge of the cube be ' l'.

So, diameter of the hemisphere = l.

Surface area of the remaining solid

= (6 - 1) faces of the cube + curved surface area of the hemisphere

= 5l^2 + 2$\pi$ (l/2)^2

= 5 * l^2 + $\pi$* l^2 * 1/2

$<b>$ That's it..

Answer 2

side of cube = diameter of of hemisphere

 r = L/2

surface area of remaining = area of one face of cube - area of circle + area of 5 reamaining faces of cube + area of hemisphere

(L² -  πL²/4) + 5 * L² + 2 π L²/4

6L² +πL²/4 = L²/4 (π + 24) unit ²
