# MENSURATION FORMULAS

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. Cylinder : Formulas :

Curved surface area of cylinder  =  2Πrh

Total surface area of cylinder  =  2Πr(h + r)

Volume of cylinder  =  Πr2h

Cone : Formulas :

Curved surface area of cone  =  Πrl

Total surface area of cone  =  2Πr(l + r)

Volume of cone  =  Πr2h / 3

Frustum Cone : Formulas :

Curved surface area of frustum cone  =  Π(R + r)l

Total surface area of frustum cone is

=  Π(R + r)l + ΠR2Πr2

Volume of frustum cone  =  Πh/3 ⋅ (R2 + Rr + r2)

Sphere : Formulas :

Surface area of sphere  =  4Πr2

Volume of sphere  =  4Πr3 / 3

Hemisphere : Formulas :

Curved surface area of hemisphere  =  2Πr2

Total surface area of hemisphere  =  3Πr2

Volume of hemisphere  =  2Πr3 / 3

Cube : Formulas :

Surface area of cube  =  4a2

Total surface area of cube  =  6a2

Volume of hemisphere  =  a3

Cuboid : Formulas :

Surface area of cuboid  =  2(hw + lh)

Total surface area of cuboid  =  2(lw + hw + lh)

Volume of cuboid  =  l x w x h
