Mensuration

Prism

Volume: (Base area)(Height)

Surface Area: 2(base area) + (Perimeter of base area)(Height)

Cylinder

Volume:

Closed cylinder:

(Base area)(height)

= πr2h

Hollow cylinder:

πR2h -πr2h

(don’t memorize)

Pyramid

Volume: ⅓(base area)(height)

Surface Area: Base area+area of n no. of lateral triangles.

*For rectangular pyramids,

Surface Area: Base area + area of 2 small triangles + area of 2 big triangles

Cone

Volume: 1/3πr2h
Surface Area:

Curved surface area:

πrl (l is the slant height)

Total surface area:

πrl + πr2

Sphere

Volume:

Total: 4/3πr3

Hemisphere: 2/3πr3

Surface Area:

Total curved surface area:4πr2

Hemisphere curved surface area: 2πr2
