    20.1246118 or 20.12

    Step-by-step explanation:

    First draw the box with the diagonal, as you can see it is split into 2 equal right triangles.

    Now use the pythagorean theorem (a^2+b^2=c^2) to find the length of the diagonal

    A^2 + b^2 = c^2

    18^2 + 9^2 =

    324 + 81 = c^2

    405 = c^2

    take the sq root

    = around 21.12
