A "right" prism has a lot of "right" angles in it. A right prism looks a lot like a box. So the most common angle in a right prism is 90.

'; explain[1] = '#2

All the angles in a right prism are equal to 90 degrees. So all the angles are equal.

'; explain[2] = '#3

The area of a prism is equal to the perimeter of the base times by the height or ph.

'; explain[3] = '#4

The volume of a prism equals area of the base times the height of bh

'; explain[4] = '#5

The volume of a pyramid equation is bh/3 so the variables are "b,h"

'; explain[5] = '#6

The total surface area of a pyramid can be found, using the formula L=.5pl

'; explain[6] = '#7

The formula for the volume of a cylinder is PI(r^2)h

'; explain[7] = '#8

The formula for the area of a cylinder is 2PIrh+2PI(r^2)

'; explain[8] = '#9

The cone volume equation is PI(r^2)h/3. This equation has 2 variables.

'; explain[9] = '#10

The volume of a sphere is computed using the formula "4PI(r^3)/3". So if the radius is 5 we plug it in and get 4PI125/3 which then simplifies to 500PI/3
