Area and Perimeter of

Cylinders

Perimeter:pi x height x Radius x Radius

Area:2 x pi x radius x radius + height(length x breadth)

Prisms

Perimeter of prism=2(Length x Width)

Area=Length x breadth(x2)

Cuboids

Area of cuboid:L x B x H. Perimeter of cuboid:L x B

Cube

Area of Cube:L x B x H.Perimeter: L x B

Volume and surface area of

cylinders

volume:area of cross section x height or base area x height

cubes

surface area:sums of the area of all faces

prisms

volume:area of cross section x height surface area:perimeter of the base x height plus 2 x base area

cuboids

volume:length x breadth x height surface area:sums of the area of all faces
