Question

I used d = L^2 + W^2 + H^2 to help me solve this but the answer just didn't come out right.

Answer 1

Did you take the square root of the sum after you calculated L^2 + W^2 + H^2 ?

Answer 2

yes, that left me with a decimal.

Answer 3

What was the exact answer? Square root of what?

Answer 4

428

Answer 5

Does that factor?

Answer 6

you mean like does it simplify or does it go with what is given?

Answer 7

Prime factorization of 72: 72 = 2 * 2* 2 * 3 * 3

Do that with 428 so that we can simplify the radical.

Answer 8

okay, give me a sec to do that

Answer 9

No rush.

Answer 10

okay, also I finished and I was left with 107, if I tried factoring that I'd be left with a decimal

Answer 11

So, 428 = ? times ? times 107?

Answer 12

2 * 2 * 107

Answer 13

Correct.
