48÷2(9+3) = ???

[MrTamago]

I left the height out on purpose, I wanted to see if you knew what you were talking about. Also it's 1/2(B+b) x h for area x l to get volume of a trapezoid. I didn't even attempt to understand what you're talking about. Plus you would have to convert inches/feet to feet/inches. Though I didn't know dividing by 231 would get the answer, I always converted to feet, and then multiplied by 7.48.

I don't see why anyone would learn how to do volume the way you did, and if they did, how they could remember it, you looked that up online didn't you?

I voted 2.

48
===== = 2
2(9+3)

It's more easy than you think...

The question was:
48÷2(9+3) = ???

So obviously the answer is 288

If the question would have been:
48÷2(9+3) = ?

Then of course the answer would have been 2

You all lose, I win!

That is the order in which you solve sums.

I believe what you just mentioned is for the total volume of the trapezoid. You mentioned it was 29% full of water and asked how much water there was, this of course adds another variable and explains the 0.29h.

I practice environmental law and do a fair amount of work with contaminated properties under RCRA/CERCLA which means I look at tank capacity and canal/ditch treatment capacity quite a bit. I tend to check the math from the engineers/consultants and believe it or not sometimes I have to correct them. A couple science degrees help. I've had quite a bit of physics, calc, etc.

You just blew my mind. What about

48÷2(9+3) = ??

I understand how your math works, it was just so much more complicated than it needed to be, that's the part that didn't make sense to me.
