What is the approximate length, in centimeters, of the diagonal from point A to point B in the right rectangular prism shown? Round your answer to the nearest whole centimeter. A.8
B.9
C.10
D.11

11

Step-by-step explanation:

First, find the diagonal along the base of the prism. Let B be the diagonal along the base.

8^(2)+6^(2)=b^(2)

64+36=b^(2)

100=b^(2)

10=b

Then let d be the diagonal from point A to point B

b^(2)+5^(2)=d^(2)

10^(2)+5^(2)=d^(2)

100+25=d^(2)

125=d^(2)

\sqrt(125)=d

11=d

Next time make sure to include a picture! This way we know were answering the correct problem :)

sorry, i can't understand your question. will later if you describe more clearly!

: )

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.
