  1. yeah, i just noticed that....i have a horrible teacher and i copied it down off the board...so what i found of the internet is that Surface Area is just the Area of the Triangular Faces summed up is true...that helps alot
  2. OK...ive been using the Formula SA of Pyramid = Area of Base + (1/2 * Perimeter * Slant Hieght but i just read this:Surface Area: Add the area of the base to the sum of the areas of all of the triangular faces. The areas of the triangular faces will have different formulas for different shaped bases it doesn't seem to be the same thing...which one is correct?
  3. true...i really don't mind which shape i can find...if its either a rectangular-based pryamid or a triangular pyramid...or even a triangular prism...as long as it reaches those requirements...thats all that matters...it can even be a cone The Formulas for Pyramids : V= 1/3 * Area of Base * Hieght I BELIEVE THIS IS THE FORMULA FOR SA OF A PYRAMID= Area of Base = (1/2*Perimeter*Slant Hieght)
  4. woops, i take that back...even when i do the SA-40=V, it still didn't work...i seriously need help...please
  5. hell no...the US is suppose to me the 'mediator' screw that...the US DOESN'T HAVE A MORAL OBLIGATION TO HELP ANYONE! Look at iraq, the the US wasn't so adiment of destroying Iran...Saddamn Hussein wouldn't have been in power...so the point im making is that many of the reasons of why there is opression in the int'l community is BECAUSE of mitiagation installed in the first place...
  6. SA= (2*area of base) + (Perimeter * Hieght) V= (Area of Base * Hieght * 1/3) Thats for a PRISM the thing about SA-40=V...i've tried it before, it gives an amazing margin of around 87 cm, but it doesn't meet the requirement of the volume being greater or equal to 360 cm cubed...otherwise it would be fine...if that doesn't make sense just tell me and ill further explain it...thank you for your help
  7. well thats my problem....i add in random numbers and it doesn't help...i mean i get really close but not close enough...then i try to alter it minorly and then it just goes no where...thanks though
  8. Im a total idiot and i can't find a pyramid or a triangular prism that was a surface area that is less than its volume by a 40 cm margin.. If you could find a triangular prism/ pryamid that has no more than 320 cm squared and at the same time has a volume of over 360 cm cubed....i would really apprieciate it thank you soo much
