NeoPets Riddles (Lenny Conundrums) and Answers Here

yay, just joined this site for the sake of the lenny conudrums XD. I got 4 digits, but im not sure about the sum of it D= i don't relly understand it. It did take me awhile googling what the conversion of inches and feet are since the country I come from doesn't use them XD.

Oh geez. I didn't even think about that. I feel stupid now. Hard math messes with your brain. I'm guessing I'm just using the wrong formula. I got it off of wikipedia, so that's probably why.

I'm using a calculator online.. :OO

i am also from a "metric" country, so these things need to be googled
and regarding the sum of the digits - here is an example:
if an answer was 62049, the sum of the digits would be 6+2+0+4+9
so we would post here: 5 digits, sum of 21

There are 12 inches in a foot, for those of you from metric communities

But how many square inches are in a square foot?
Cubic inches in a cubic foot?

These are the questions we must answer.

i got 5 digits with a sum of 25 d=

That's probably how I'm messing up. I'm just dividing by 12.

I figured it out!!!!!
I was using 144 instead of 1728 for the division!
So each cube foot is 1728 cube inches!
do not use 144.

Did you guys get an anwser yet?

I got little confused of the numbers, haha! I want to share something very funny video about a pet. Try to watch! The smartest dog in the world!

@beebzzz yay thankyou =) awesome, that means i got 4 digits sum of 25 ^_^

oops. do not use 12
use 144

4 digits, sum:25
I gots it!

Oh wait, we are all wrong.
should be a three digit

actually since it is a cubic foot, you must use 12^3, i.e. 1728.

and it is 4 digits, sum of 25 - i am certain of it.

How do you know it should be a 3 digit DX, i have a feeling not many people are gonna get it right this week lol.

I'm so ticked. I had the right answer when I worked it out. But I typed it in wrong.

Solution to the most recent LC:

We have 375 pies, in a pie shape with a height (h) of 2.8 inches, a radius (R) at the top of 5.5 inches and a radius (r) at the bottom of 4.25 inches (half the specified diameter of 8.5 inches).

The pie shape is a conical frustum (probably upside-down compared to most illustrations). According to Wolfram Mathworld at http://mathworld.wolfram.com/ConicalFrustum.html, the volume is:

V = (1/3)h * pi * (R^2 + Rr + r^2).

Plugging in our values, we get V = 210.1987285 cubic inches.

Now the density of the pies is 171.6 pounds per cubic foot, so we need to convert the volume into cubic feet. A foot is 12 inches, so the volume V of a single pie is V = 210.1987285 / 12 / 12 /12 = 0.121642783 cubic feet. Multiply this times 375 pies and 171.6 pounds per cubic foot to get a total weight of 7827.713065 pounds. Round this to 7828 to submit.

(Although they don't explicitly indicate the units they want the weight in, the clear assumption is that it should be in pounds, as the only unit of weight mentioned in the problem.)

well, I got it wrong.
anyone else got it wrong?

Wow, almost 6pm NST and still not out - wonder what's keeping them.
