Equations we will cover
This is from the equation sheet that you will get for your regents.
You just need to know what the letters mean and be able to rearrange the equations.
You will notice that the 2-D figures have a lowercase b
whilst
The 3D shapes have a capital B
This is because "B" is the area of the base. While "b" is base length

Moving 2D figures into 3D space
2-D shapes when rotated around a segment or line will form 3-D figures. Each point will travel in a circular motion around the segment or line.
Cross sections
Cross sections are the 2-D shape we see when we 'cut' a shape in a straight line.
Each solid with have a number of possible cross sections. However most people recognize the base shape easiest

Volume equations
Despite being given all the equations, you need to know how to use them.
Below of practice sheets and a video to help with using the different equations.

Density
The density of an item is how heavy it is compared to it's volume. Or how tightly it's particles are packed
