Areas and Volumes
The equations here will be familiar to most users and are to demonstrate calculations with BlackBox
These are formulas to find the area and volume for various shapes. 
If you load in the Math file called Area and Volume, the symbols like Base and Height will be ready to use in calculations straight away. If you want to use these equations without loading in this file, use the equations and teach the meanings of the symbols to BlackBox. This is how you make new files of symbols and equations that you can reuse when you need them.

When in the Notepad (this page), a blue underline means Hypertext - clicking on it will load the underlined text into the calculator (saves retyping).

The formulas
Rectangle
Area = Base * Height

Parallelogram
Area = Base*Height [Parallelogram]

Trapezoid
Area = ½Height*(a+b) [Trapezoid ->Parallel sides a & b]

Circle
Area = Pi r² [Circle]
Circumference = 2 Pi r [Circle]

Triangle
Area = ½Base * Height     [Triangle]

Cube
Volume = Length³     [Cube]
SurfaceArea =  6Length²   [Cube]

Rectangular Prism
Area = Length * Width * Height     [Rectangular Prism]
SurfaceArea =2( (Width*Length)+(Height*Width)+(Height*Length))  [Rect Prism]

Sphere
Volume = ¾ Pi r³    [Sphere]

Triangular Prism
Volume = ½Base*Height*Length   [Triangular Prism]

Trapezoidal Prism
Volume = ½(a+b)*Height*Length      [Trapezoidal Prism]

Cone
Volume = (Pi r² Height) / 3    [Cone]

Pyramid
Volume = (Length*Base*Height)  / 3 [Rectangular Pyramid]
Volume = (Length*Base*Height)  / 6 [Triangular Pyramid]

Cylinder
Volume = Pi r² Length     [Cylinder]
SurfaceArea = 2 Pi r² + ( 2 Pi r² Length)   [Cylinder]
