✴here is your answer ✴
======================
1. surface area of a cuboid=2(lb+bh+hl)
2. surface area of a cube=6a²
3. curved surface area of a cylinder=2πrh
4. total surface area of a cylinder=2πr(r+h)
5. curved surface area of a cone=πrl
6. total surface area of a right circular cone=πr(l+r)
7. surface area of a sphere of radius=4πr²
8. curved surface area of a hemisphere=2πr²
9. total surface area of hemisphere=3πr²
10. volume of a cuboid=l×b×h
11. volume of a cube= a³
12. volume of a cylinder=πr²h
13. volume of a cone=1/3πr²h
14. volume of a sphere of radius=4/3πr³
15. volume of a hemisphere=2/3πr³
I hope you understand
