Knowing how to find the volume of cubes, cones, spheres and other basic figures is really important for algebra students. If you know how to apply the following formulas you will be fine- make sure you use the right units of measure!

Some key concepts to remember about area and volume:

* area is measured in units squared; example 24 inches squared or 61 mm squared

* volume is measured in units cubed; example 109 inches cubed or 83 cm cubed

* when calculating area or volume make sure all the input values into your formula have the same units first

* when using pi (3.14) the more digits of pi you use in you calculation the more accurate your answer- don’t round off too much
