To find the longest diagonal that can fit completely inside the juice can, we need to find the diagonal of a rectangle formed by the height and the diameter of the cylinder.

The diagonal of a rectangle can be found using the Pythagorean theorem. The equation is:

diagonal^2 = height^2 + diameter^2

Substituting the given values into the equation:
diagonal^2 = 122^2 + 52^2
diagonal^2 = 14884 + 2704
diagonal^2 = 17588

Taking the square root of both sides to solve for the diagonal:
diagonal ≈ √17588
diagonal ≈ 132.6 mm

Therefore, the longest straw that can fit completely inside the juice can diagonally is approximately 132.6 mm. Rounded to the nearest tenth, it is 132.6 mm.
