Hehe. How did you get 46?

Sorry, yes 46 is wrong.
From what I understand, the smallest pyramid requires 10 balls, the next should be 19 balls, 31,46,........and so on.
It's not possible to make a bigger pyramid using all the balls from two smaller pyramids.

Nice analysis. But you are still wrong. Notice the pattern with which the balls are placed, STRATUM by STRATUM

Notice in the given example. 10 + 10 balls i.e 1+3+6 and 1+3+6 gave 20 balls i.e 1+3+6+10. Your job is to deduce an (algorithm) that can generate a pyramid using two unequal pyramids.

The answer is 725 balls, 120 balls from the smaller pyramid and 605 balls from the bigger pyramid.

Waiting for my prize, lol.

Really. I think I have gotten it now.

haha. Your answer too far. Ha! Wetin! Explain your steps sha

For the steps, well well well, I just did it some how sha.

The number of balls needed for the smallest pyramid is 10, 20 for the next size, 35, 56, 84, 120,165, 220,.......... 605, 725....... and so on, using these 4+6+10+15+21+28........

120 and 605 are the only (maybe the first set of) numbers that will add up to another number in the sequence.
What's your answer? Am still waiting for my prize.

There are 2 answers. 14 and 30. But based on the question 30 is more correct.:p

Okay. Although I don't understand.

Hope you know you can't have a pyramid with 30 balls or even 14balls

In short, your answer is wrong. LOL

sparklebaby:


Okay. Although I don't understand.

Actually I am wrong. I don't even know what a tetrahedral pyramid is. I just checked the meaning.

sparklebaby:
Hope you know you can't have a pyramid with 30 balls or even 14balls

this i s a tetrahedral pyramid. Not just an ordinary pyramid.
The answer is actually 10.

The answer is actually 168.
Sorry hear.

LOL, there is no answer to the question jare.

sparklebaby:




LOL, there is no answer to the question jare.

No na. Those ones na typographical error.
See. You look for the difference between two small pyramids such that the difference itself can form a pyramid.
So our options are 1,3,6,10,... I.e
1,3,6,10,15,21,28,36,45,55. You see! 55-45=10. Gbam! So add 1;3;6 down to 55. That gives you 220. Lol.

Where my pen

Alright. What is a pyramid

You are still wrong. My answer 725 is correct. Just settle down and think about it, if 220 is the answer then what number was used for the small pyramid and what was used for the bigger one.

A pyramid is made up of four triangular surface.

lol. So wat series did you add up to give 725

I added these; 4+6+10+15+21+28+36+45+55+66+78+91+105+120 when you add all these you have 725.

lie. I got 680. Now add 136. U get 826.

timonski:

My bad, made wrong calculation.
The answer 680 then, 120 balls for small pyramid and 560 for the bigger one.

You still haven't answered my question. 'if 220 is the answer then what number was used for the small pyramid and what was used for the bigger one?'

what sum gave you 120?
