Answer 3

after solving it

Answer 4

okay now ill simplify that

Answer 5

uh... i got \[6\sqrt{7}\]

Answer 6

after simplifying it

Answer 7

I'm confusedddd @Mehek14

Answer 8

I think you'll have to find a face diagonal first.

Square root of (24^2 - 18^2 ) is not correct.

Answer 9

>>What is the diagonal length of the suitcase

I assume diagonal is the diagonal of the solid and not a face diagonal.

Answer 10

uh--- so what would I do nnow?

Answer 11

Apply the correct formula.

Answer 12

We don't know the 3 dimensions of the solid.

We will have to use another approach.

Answer 13

um.. so wouldn't I add \[18^{2} + 24^{2} ?\]

Answer 14

I think that this problem uses the word "diagonal" to refer to a face diagonal of one of the rectangular faces of the suitcase.

There is also a diagonal of the rectangular solid.

The problem should have made this clear or perhaps a given diagram was not posted.

Look at the attachment.

Answer 15

Oh ok I see @Directrix

Answer 16

Do you have that suitcase diagram on your homework questions?

Answer 17

Without a graphic or a set of answer options, I don't know which diagonal is meant by the problem.

It appears now to be a face diagonal.

Answer 18

yeah it's there @Directrix

Answer 19

I guess that is a wrap for this problem.

Answer 20

Alrighty thank you so much for your help @Directrix

Answer 21
