Summary

1. Volume of a cube = (side)3 cu. units  

2. Surface area of a cube = 6(side)2 sq. units

3. Volume of a cuboid = lbh cu. units

4. Surface area of a cuboid = 2(lb + bh + hl) sq. units

5. Volume of a cylinder = πr2h cu. units

6. Curved surface area of a cylinder = 2πr × h sq. units

7. Total surface area of a cylinder = 2πr(r + h) sq. units

8. Volume of a cone = π r2h cu. units

9. Curved surface area of a cone = πrl

10. Total surface area of cone = πr2 + πrl = πr(r + l) sq. units

11. Volume of a sphere = πr3

12. Surface area of a sphere = 4πr2

13. Volume of a hemisphere = π r3 cu. units.

14. Total surface area of a hemisphere = 3πr2

15. Curved surface area of a hemisphere = 2πr2

16. Volume of a frustum =π (R2 + Rr + r2)h
17. Lateral surface area of a frustum = π (R + r)l
18. Total surface area of a frustum = π (R + r)l + πR2 + πr2
