Geometry Formulas ► Perimeter

Perimeter of a square: [ s + s + s + s ]
s : length of one side
Perimeter of a rec tangle: [ l + w + l + w ]
l : length
w : width
Perimeter of a triangle: [ a + b + c ]
a, b, and c: lengths of the 3 sides

Geometry Formulas ►Area
 Area of a square : [ s . s ]
s : length of one side

Area of a rectangle : [ l . w ]
l : length
w : width

Area of a triangle : 1/2 . [ b . h ]
b  : length of base
h: length of height

Area of a trapezoid: 1/2 . [ b1 + b2 ] . h
b1 and b2 : parallel sides or the bases
h : length of height

Geometry Formulas ► volume
Volume of a cube: [ s . s . s ]
s : length of one side
Volume of a box:  [ l . w . h ]
l : length
w : width
h : height
Volume of a sphere: (4/3) × pi × r³
r : radius of sphere

Volume of a triangular prism: area of triangle . Height = (1/2 base × height) .Height
Base :  length of the base of the triangle
Height : height of the triangle
Height : height of the triangular prism

Volume of a cylinder: pi . r² . Height
pi : 3.14
r : radius of the circle of the base
Height : height of the cylinder
