For calculations, Lateral Surface Area means curved surface area. It's called lateral surface area for cube and cuboid and curved surface area for cylinder, cone and hemisphere.

The formulas for calculating Surface Area and Volume are

 

Cube

  • Lateral Surface Area = 4a2
  • Total Surface Area = 6a2
  • Volume = a3

 

Cuboid

  • Lateral Surface Area = 2(lh + bh) = 2 (l + b) h
  • Total Surface Area = 2(lb + bh + lh)
  • Volume = l x b x h

 

Cylinder

  • Curved Surface Area = 2πrh
  • Total Surface Area = 2πrh + πr2 + πr2 = 2πrh + 2πr2 = 2πr(r + h)
  • Volume = πr2h

 

Cone

  • Curved Surface Area = πrl
  • Total Surface Area = πrl + πr2 = πr(r + l)
  • Volume = 1/3 πr2h

 

Hemisphere

  • Curved Surface Area = 2πr2
  • Total Surface Area = 2πr2 + πr2 = 3πr2
  • Volume = 2/3 πr3

 

Sphere

  • Surface Area = 4πr2
  • Volume = 4/3 πr3

Frustum

  • Curved Surface Area = π(r1 + r2)l
  • Total Surface Area =π(r1 + r2)l + πr1+ πr22
  • Volume = 1/3 πh (r12 + r22 + r1r2)
