Answer:
Step-by-step explanation:
Diameter or cylinder = 7 cm
Radius = 7/2 cm
SA of remaining= SAcuboid -2(area of
Solid. Circle)
= 2(lb+bh+hl) - 2(πr^2)
= 2(15×10 + 10×5 + 5×15)
- 2(22/7×7/2×7/2)
= 2(150+50+75) -2(77/2)
=2(275) - 77
= 550-77
= 473 cm square
Srry its wrong
Sorry guys it's wrong
I know
correct is 583 sq. cm
S.A. of remaining block=S.A. of cuboid + C. S. A of cylinder - S. A. of two circular ends of cylindrical hole
