Elegant Algebraic Formulas

Sunday, October 18, 2009
Hi, again... this is going to be my second post for today and it's going to be about the most "Elegant Algebraic Formulas" to use for finding the surface areas for certain shapes.

The most elegant algebraic formula for find the cube's surface area is S.A=6s², because there are 6 faces and each side is a certain measurement.

The best or I mean the most elegant algebraic formula for finding the Surface area for the Rectangular Prism is in the picture below..


And Finally the elegant algebraic formula for finding the Surface area for the Cylinder is again, located in the picture below...

Nice post! I really liked the pictures you used. I thought you could have used color to highlight important things, but it was very good overall.

Great job Marc! Your explanations are very clear, and your pictures and examples are very helpful to the reader. Although, I agree with Kristin about adding some colours. Also, about our rectangular prism formula. When you used this formula---> 2(hl+hw+lw), you should've sticked with it throughout the entire equation. But instead, you used this formula---> 2(hl)+2(hw)+2(lw). I'm not saying it's wrong, it's just that people who read this might get confused. They're both right formulas, I'm just saying to just use one. But overall, AWESOME WORK!

Hi there Marc! I also agree with Melanie and Kristin that you should add a few colours to your post. Other than that, great job! (:
