In this video we will get to learn about the surface areas and volumes of different solids having identical top and base.

  • General formula for finding the surface area of solids having identical top and base is = Area of base × height
  • Surface area of solids having identical top and base is of two types:

           a) Lateral Surface area = perimeter of base  ×  height
           b) Total surface area = lateral surface area + 2 × area of base 4.

  • Volume of a cuboid = l × b × h
  • Lateral surface area of a cuboid = 2h (l + b)
  • Total surface area of a cuboid= 2 (lb + bh +  hl)
  • Relation between liters and cubic meters: 1 m3= 1000 litres
  • Volume of a cube = (side)3
  • Lateral surface area of a cube = 4(side)2
  • Total surface area of a cube = 6(side)2
