for a triangular prism, its volume will simply be <u>area of its base</u> times its length.
the are of the base for this one is simply any of those triangular bases. Now, let's notice, the right-triangle has a base of 9 and a height o 9, notice the tickmarks, whilst the prism also has a length of 13.
![\bf \stackrel{\textit{area of the triangle}}{\cfrac{1}{2}(9)(9)}~~\cdot~~ \stackrel{\textit{length}}{(13)}\implies 9\cdot 13\implies 117](https://tex.z-dn.net/?f=%5Cbf%20%5Cstackrel%7B%5Ctextit%7Barea%20of%20the%20triangle%7D%7D%7B%5Ccfrac%7B1%7D%7B2%7D%289%29%289%29%7D~~%5Ccdot~~%20%5Cstackrel%7B%5Ctextit%7Blength%7D%7D%7B%2813%29%7D%5Cimplies%209%5Ccdot%2013%5Cimplies%20117)
<span>One method of converting a fraction into a decimal is dividing the fraction's numerator (the top number) by its denominator (the bottom number). Hope this help</span>
Do 55,427 divided by 67,103 which is 0.825998838 then multiply that by 100 to get 82.5998838 then round up to the nearest tenth to get 83 percent
