Question

what is the length of the diagonal for the given rectangular prism to the nearest whole unit? Length:12cm, Width:4cm, and Height of 9cm. .My answer: 15cm.

Answer 1

If I recall correctly the way you do this problem is:
\[\sqrt{12^2 + 4^2 + 9^2}\]
\[=\sqrt{241}\]
\[=15.52417\]

So yes I agree with you 15cm sounds good.
Though if we want to round to the nearest WHOLE number, because it is \(15.52\) we round up making it 16cm.

Answer 2
