  1. Surface area and volume Project work on Mathematics

  2. CUBE :- A solid three-dimensional geometric figure bounded by six planes; each of the six sides or faces of a cube is a a2 a3 a1

  3. a FINDING THE SURFACE AREA OF CUBE. a a a a a a a a a a a

  4. FINDING LATERAL SURFACE AREA OF CUBE:-

  5. FINDING THE VOLUME OF CUBE :- a a a

  6. CUBOID :- A three-dimensional geometric figure formed of six rectangular plane faces, each set at right angles to the four sides adjacent to it. h b l

  7. l b b l h FINDING TOTAL SURFACE AREA OF CUBOID:- h h h l b b l

  8. FINDING LATERAL SURFACE AREA OF CUBOID :-

  9. FINDING VOLUME OF CUBOID:- h b l

  10. r h CYLINDER:- Cylinder consists of two circular bases of equal area in parallel planes, that are connected by a lateral surface that intersects the boundaries of the bases.

  11. FINDING CURVED SURFACE AREA OF CYLINDER:- r h

  12. TOTAL SURFACE AREA OF CUBOID :- r h

  13. Finding Volume of cuboid :- r h

  14. l h r CONE :- A surface generated by a straight line that moves along a closed curve while always passing through a fixed point.

  15. FINDING CURVED SURFACE AREA OF CONE :- l h r

  16. Finding total surface area of cone :- l h r

  17. Finding volume of cone :- l h r

  18. r SPHERE :- Surface of which every point is the same distance from a fixed point known as the centre. From every aspect it has the same appearance. A sphere may be described by the rotation of a semicircle or circle, about its diameter.

  19. FINDING SURFACE AREA OF SPHERE :- r

  20. FINDING VOLUME OF SPHERE :- r

  21. r Hemisphere :- ‘Hemi’ also means ‘half’. So When Sphere is Divided into two equal parts Each equal part is called Hemisphere

  22. Finding curved surface area of hemisphere r

  23. TOTAL SURFACE AREA OF HEMISPHERE r

  24. Volume of hemisphere r
