I'm assuming we are not given a calculator/pen and paper, and so we can't measure the three lengths and calculate the desired length.

In that case, place one of the blocks on a table, for reference call its top face rectangle ABCD. Now, place a second block in the same orientation adjacent to the first (so if the new block is EFGH, points A and H will be adjacent and G and B will be adjacent). Place the third block in the same orientation directly on top of EFGH. The desired length can then be measured from the point on the upper block directly above H (= A) to point C on the original block.
