Hi Vasu,
For caclulations, 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 formulae 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
