Surface areas and volume

  1. 1. Made By – Ayushi Raturi
  2. 2. FiguresSolid PlaneFig. Fig.
  3. 3. Closed Cuboid and Open Cuboid 5 1 3 4 6
  4. 4. Area of rectangle 1 = (l x h) +Area of rectangle 2 = (l x h) +Area of rectangle 3 = (l x b) +Area of rectangle 4 = (l x b) +Area of rectangle 5 = (b x h) +Area of rectangle 6 = (b x h) =2(l x b) + 2(b x h) + 2(l x h) =2(lb + bh + hl)
  5. 5. h Base area = l x b Height = h So, Volume of a cuboid b =lxbxhl
  6. 6. Closed cube and Open cube 5 1 2 3 4 6
  7. 7. Area of square 1 = a xa Area of square 2 = a xa Area of square 3 = a xa Area of square 4 = a xa Area of square 5 = a xa Area of square 6 = a xaSurface area = Area of all six faces = 6a2
  8. 8. a Base area = a Height = aa So, Volume of a cube = a3
  9. 9. CURVED SURFACE AREA OF A CYLINDER Circular Curved surfaces surface areaArea of curved surface + Area of two circular surfaces =(2 π r) x( h) + 2 π r2 = 2 π r( h+ r)
  10. 10. Area of circular base =π r2Height = hSo, Volume of acylinder= π r2 x h
  11. 11. l lr
  12. 12. lAfter cutting the cone, θCurved surface area = Area of the sector r
  13. 13. l + r lr Total surface area =π r2 + π r l
