Question

Please help.
-----------
Problem below!
The height is multiplied by 3.
Then the area increases by 3*3=9

So would it be 3x or are they asking for the final product which is 9?

Answer 1

@Nurali That's where I'm confused- are they asking about when it's "tripled".. or the final product "nine"?
I'm confused!

Answer 2

@ganeshie8 and @amistre64
I am confused because they are both options and I'm not positive what part they are asking for.

Answer 3

surface area: 4(6n*9n)/2 + (9n)^2

let n=1, and let n=3 and compare the results

4(54)/2 + 81 = 189

4(18*27)/2 + (27)^2 = 1701

so its going to be bigger by 1701/189

Answer 4

= 9

Answer 5

logically, the area will be bigger; so 3 or 9 times bigger; and since area is affected more than linear, 3times on the linear will be more than 3times on the area

Answer 6

but yes, mathically it comes to 9

Answer 7

In other words , you are saying it is either 3 or 9x bigger;
given to the calculations we've done, it can only be
nine times the original pyramid’s surface area, correct?

Answer 9

yep
