Surface Areas and Volumes

Surface Areas and Volumes

1. Surface area of a cuboid = 2(lb+bh+hl)

2. Surface area of a cube = 6a square

3. Curved surface area of a cylinder = 2 pie rh

4. Total surface area of a cylinder = 2 pie r(r+h)

5. Curved surface areas = pie rl

6. Total surface area of a right circular cone = pie rl + pie r square pie r (l+r)

7. Sueface area of a sphere of a sphere of radius r = 4 pie r square

8. Curved surface area of a hemisphere = 2 pie r square

9. Totl surface area of a hemisphere = 3 pie r square

10. Volume of cuboid = l * b * h

11. Volume of cube = a cube

12. Volume of cylindr = pie r square h

13. Volume of cone = 1/3 pie r square h

14. Volume of a sphere of radius r = 4/3 pir r cube

15. Volume of hemisphere = 2/3 pie r cube
