Square area = side length × side length s = a 2

Parallelogram area = base × height S=ah

Trapezoidal area = (upper bottom+lower bottom) × height ÷2S=(a+b)×h÷2.

Area of circle = π× square of radius s = π r 2

Sector area = pi × square of radius× degree of central angle ÷ degree of central angle S = π r 2 × n ÷ 360.

The surface area of a cuboid = (length× width+length× height+width× height )× 2s = (AB+AH+BH )× 2.

Surface area of cube = square of side length× 6s = 6a2.

Cuboid volume = length× width× height V=abh

Cube volume = cube with side length v = a 3

Side area of cylinder = bottom circumference x height S=Ch=πdh=2πrh.

Surface area of cylinder = lateral area+bottom area× 2s = 2π RH+2π R2.

Cylinder volume = bottom area × height v = SH = π r 2h

Cone volume = bottom area × height ÷ 3v = sh ÷ 3 = π r 2h ÷ 3

Bottom× height ÷2S=ah÷2
