In this section, we are going to see mensuration formulas which can be used to find cured surface area, total surface area and volume of 3-D shapes like cylinder, cone and sphere.


Curved surface area of cylinder = 2πrh
Total surface area of cylinder = 2πr(h + r)
Volume of cylinder = πr2h

Curved surface area of cone = πrl
Total surface area of cone = 2πr(l + r)
Volume of cone = πr2h/3

Curved surface area of frustum cone = π(R + r)l
Total surface area of frustum cone is
= π(R + r)l + πR2 + πr2
Volume of frustum cone = πh/3 ⋅ (R2 + Rr + r2)

Surface area of sphere = 4πr2
Volume of sphere = 4πr3/3

Curved surface area of hemisphere = 2πr2
Total surface area of hemisphere = 3πr2
Volume of hemisphere = 2πr3/3

Surface area of cube = 4a2
Total surface area of cube = 6a2
Volume of hemisphere = a3

Surface area of cuboid = 2(hw + lh)
Total surface area of cuboid = 2(lw + hw + lh)
Volume of cuboid = l x w x h
