Consider the following figure. The base is a triangle with two side of the same length 10cm and one side of length 12cm. The height of the prism is 16cm.

Use Pythagoras' Theorem to find the unknown height $x$ in the triangular prism shown.
Please directly answer the question and provide the final value, e.g., 1, 2.5, 300.
