Geometry Formulas and Concepts

What is the difference between a capital B and a lower case b in a geometry formula?

• B=bottom side

  b= area of the bottom of a 3-d figure

• B= area of the bottom of a 3-d figure

  b=bottom side

• B= volume of a 3-d figure

  b=area of the bottom side

• B= area of the bottom side

  b=volume of a 3-d figure
