Best ResponseYou've already chosen the best response.2Volume of a pyramid = ( Length x Width x Height ) / 3 if the base is a square: Length = width so Volume of a pyramid = ( Length x Length x Height ) / 3 \(\Large V = \frac{L \times L \times H}3\) if you have the volume and the height... can you solve this for Length?

Best ResponseYou've already chosen the best response.0would the length be 576 and the height 3?

Best ResponseYou've already chosen the best response.0oh ok sorry um.. im just wondering idk what length would be because i only have volume and height

Best ResponseYou've already chosen the best response.2sók... yep, we're trying to solve the length if u plug the values for volume and height into the above equation... you should be left with L^2 = ... a number

Best ResponseYou've already chosen the best response.0ok 576/3 would be 192 right ??

Best ResponseYou've already chosen the best response.2\(\Large V = \frac{L \times L \times H}3\) \(\Large 576 = \frac{L \times L \times 3}3\) \(\Large 576 = \frac{L \times L \times \color{red}{3}} {\color{red}{3}}\) \(\Large 576 = L \times L \) \(\Large 576 = L^2 \) \(\Large \sqrt{576} = \sqrt{L^2} \) \(\Large \sqrt{576} = L \)

Best ResponseYou've already chosen the best response.0i was just confused at the part of where we had to find the length. but that chart u showed does help a little

Best ResponseYou've already chosen the best response.2cools... so how'd u go at solving, did u get an answer for L = ...?

Best ResponseYou've already chosen the best response.0@Jack1 i dont understand what to next in the equation i keep getting confused

Best ResponseYou've already chosen the best response.2ok, well lets back it up, and you tell me which step ur having trouble with and we'll go through it together so just say yes or no after each step, and well either keep going or explain more so 1. \(\Large V = \frac{L \times W \times H}3\) 2. "base of a square pyramid"... so from question, we know it's a square pyramid so the base is a square Length = Width new equation: \(\Large V = \frac{L \times L \times H}3\) all cool so far?

Best ResponseYou've already chosen the best response.2nice 3. from the question again: "Find the length .... if the volume is 576 cubic inches and has a height of 3 inches. " so find L if V = 576 and h = 3 put the values of V and H into our equation new equation: \(\Large V = \frac{L \times L \times H}3\) \(\Large 576 = \frac{L \times L \times 3}3\) still with me?

Best ResponseYou've already chosen the best response.2all good 4. there's a 3 top and bottom in the fraction, so it's times 3 and then divide by 3... so they cancel eachother out \(\Large 576 = \frac{L \times L \times \color{red}{3}} {\color{red}{3}}\) \(\Large 576 = \frac{L \times L \times 1} 1\) \(\Large 576 = L \times L \) \(\Large 576 = L^2 \) all cool still?

Best ResponseYou've already chosen the best response.2got it then, sweet! so are you ok to solve from here?

Best ResponseYou've already chosen the best response.0yea i think so um.. for the last where it say 576=L/2 would then be 576= 2x2?

Jack1

Best ResponseYou've already chosen the best response.2no, that's L squared, so 576 = L x L so if you take the square root of both sides you're left with : ____ (number?) = L
