babynini · Answer

Help! The first one is a pain.

babynini · Answer

@zepdrix I've gotten answers all over the place trying to calculate it. The other two I got really fast :|

babynini · Answer

I also got 1616 
I'm doing: 8(36)+8(36)+8(32)+8(28)+8(24)+18(16)

zepdrix · Answer

So for L6 we have
8f(0) + 8f(8) + 8f(16) + 8f(24) + 8f(32) + 8f(40)

Those are the 6 rectangles ya? :o
Let's factor the 8 out,
$\rm 8\left[f(0)+f(8)+f(16)+f(24)+f(32)+f(40)\right]$

So we'll need to read this graph carefully, hmm

zepdrix · Answer

$$\rm 8\left[36+f(8)+f(16)+f(24)+f(32)+f(40)\right]$$For the second height... hmm 35 I think?

zepdrix · Answer

$$\rm 8\left[36+35+f(16)+f(24)+f(32)+f(40)\right]$$

babynini · Answer

how did you get 35? o.o so specifically? oo

babynini · Answer

so f(16) would be 33?

zepdrix · Answer

Ya that sounds about right :)
It's just above the 32 mark.

babynini · Answer

then 29,24,16?

zepdrix · Answer

mmm ya

babynini · Answer

and the answer would come out to 1384?

zepdrix · Answer

Yes, that's what I'm getting also.
