Question

The base of a pyramid is a square with dimensions 12 in by 12 in. The height of the pyramid is 10 in. What is the slant of the pyramid

Answer 1

Damn, I can't remember the formula for this. Let me look it up...

Answer 2

s² = h² + (b/2)²

Answer 3

s^2 = 10^2 + (144/2)^2

Answer 4

s^2 = 100 + 72^2

Answer 5

correction s^2 = 10^2 + (12/2)^2 b = 12 not 144. :)

Answer 6

derp

Answer 7

jvat, are you sure? I thought that the base of a pyramid was l*w

Answer 8

well, don't get caught up on the formula and focus on the geometry of the question

Answer 9

The picture is correct. Now to find the slant height you use Pythagorean's Theorem and solve for the hypotenuse.

Answer 10

the question has to do with lengths, so introducing area is not appropriate, the units would be wrong.

Answer 11

Wouldn't it come out the same way?

Answer 12

let's try it and see. :)

Answer 13

Just draw the pic using the info given and it is apparent what you need to do to solve this.

Answer 14

What did both of you get as the measure of the slant height?

Answer 15

11.66

Answer 16

And where is Edelong in all of this discussion, I wonder? lol

Answer 17

ikr

Answer 18

I got that too. (11.66)

Answer 19

My result is different. I didn't see it the way you saw it. :/

Answer 20

the problem here was in interpreting the formula

Answer 21

which is why I try to not trust formulas, it is important to understand what the situation is actually about. :)
