This document provides formulas for calculating the area, surface area, and volume of basic shapes including squares, rectangles, triangles, circles, cubes, rectangular prisms, triangular prisms, and cylinders. It lists that the area of a square or rectangle is length times width, the area of a triangle is one-half the base times the height, the area of a circle is π times the radius squared, and provides formulas for calculating the surface area and volume of 3D objects like cubes, prisms and cylinders.

1. AREA CHEAT SHEET
Square
W Area = Length (L) x Width (W)
L
Rectangle
W Area = Length (L) x Width (W)
L
Triangle
h
h H Area = Base (B) x Height (h) **If only half the base is shown then
B you DOUBLE it before multiplying**
Circle
D r r = radius D= Diameter
Area = πr2 = π x (radius x radius))

2. SURFACE AREA (SA)
Cube
SA = 6(Length x Width)
RECTANLGE
SA = 2(Length x Width) + 2(Width x Height) + 2(Length x height)
Triangle
SA = 2(Base x Height) + 2(Length x Width) + (Length x Base)
Divided by 2
Cylinder
Find Circumference of Circle first C=π x Diameter
SA = 2(Area of a circle) + Area of a Rectangle
SA = 2( ) + (Length x Circumference)
Volume (V)
V = Base (B) x Height (h)
Rectangular Prism
Base = (Length x Width)
V = Base x Height
Triangular Prism
Base = (Area of the Triangle)
V = Base x Height
Cylinder
Base = (Area of a Circle)
Base = ( ) = π x (radius x radius)
V = Base x Height
