Formula for volume and surface area of all geometry! For example: cone, cylinder, triangle, diamond, etc..

Perimeter of rectangle=(L+W)×2
Perimeter of square = side length ×4
Area of rectangle = length x width
Square area = side length × side length
Area of triangle = bottom × height ÷2
Area of parallelogram = bottom x height
Area of trapezoid=(upper bottom + lower bottom)× height÷2
Diameter = Radius ×2 Radius = Diameter ÷2
Circumference of circle = pi x diameter =
Pi × radius ×2
Area of circle = pi × radius × radius
Surface area of box =
(L×W+L×H+W×H)×2
Cuboid volume = length x width x height
Surface area of cube = prism length × prism length ×6
Volume of cube = prism length × prism length × prism length
Side product of cylinder = perimeter of bottom circle × height
Surface area of cylinder = upper and lower bottom area + side area
Volume of cylinder = bottom area × height
Volume of cone = bottom area × height ÷3
Box (Box, Cylinder)
Volume of = Bottom Area × Height
