Remembering formulas

During my geometry part of my math class, I had the hardest time remembering all the formulas to figure out area, volume, etc. I wonder if there is a good way to remember this things or if it is something you need to use more often to have it in your long term memory bank.

Common Geometry Formulas are somewhat easy for me to retrieve from my mind but Volume Formulas are a little more tricky. Some Surface Area Formulas kicked my butt like when it came to a cylinder. I struggled with understanding that I needed to find the surface area of the top and bottom separately from the cylinder side.

I did find this wonderful formula PDF that really helped me have all the formulas in one place. I actually printed and laminated it so I will always have it around. Once I started researching, I found a ton of formula sheets that would work extremely well for any age group. For example, this one would work really well for someone that is just starting out with geometry. It is really amazing how much easier studying and dealing with math is now with the Internet. Back when I was in school, your textbook was your best friend to help you through math (or maybe a few friends that could explain it better then the textbook)
