Answer 1

As you know, the diagonal of a 2-D rectangle is

√(x^2+y^2)

Similarly, the diagonal of a rectangular prism is

√(x^2+y^2+z^2)

So, since you have x,y,z just plug them in:

√(144+16+81) = √241 = 15.52

Looks like B to me.

Answer 2

It would be A because anything rounding for the decimals a thing 5 or up changes the number yw

Answer 3

i really need help please. i'll be patient but i am in a little bit of a rush.

Answer 4

15.52 is does not equal 15 it equals 16 because .52 rounds up to 1

Answer 5

It kinda seems like it's 16 but that's just me

Answer 6

I believe the answer is A because you have round to the nearest whole unit.

Answer 7

You would round up to 16 if its 15.52, so wouldn't it be A?

Answer 8

so is it A?? or B??
