Mensuration

Mensuration involves calculating the area, perimeter, volume, and surface area of various geometric shapes like prisms, cubes, cuboids, and cylinders. The area and perimeter of prisms depend on their length, breadth, and height, while the area of a cube is derived from its length, breadth, and height.

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
