Introduction to geometry formula sheet:
The Geometry formula sheet which are deals with size and shape of planes, points, solids etc. In geometry, points are Zero-dimensional shaped formed one which means the height, length, and width is not here. Line is nothing but a one-dimensional figure.
When compare to point it's length , but there is no width and height. A single line is made up of an infinite number of points. In the geometry formula sheet, it consists of classifications of formulas which are having area and perimeter of shapes and also has volume and surface area for the solids.
Formula sheet for area and perimeter:

Area and perimeter formula for square is,

Area = a²

Perimeter = 4a

Area and perimeter formula for Rectangle is,

Area = lw = length x width

Perimeter = 2(l +w)

Area and perimeter formula for Triangle is,

Area = bh = x base x height

Perimeter = a + b + c

Area and perimeter formula for Circle is,

Area = Πr²

Perimeter = 2Πr

Formula sheet for volume (V) and surface area (SA) of solids:

Volume and surface area for Cube is,

Volume = a³

Surface area = 6a²

Volume and surface area for Rectangular Prism is,

Volume = lwh = length x width x height

Surface area = 2lw + 2hw + 2lh

Volume and surface area for General Prisms is,

Volume = Bh = area of base x height

Surface area = sum of the areas of the faces

Volume and surface area for Sphere is,

Volume = 4Πr³

Surface area = (4/3) Πr²
