You are given three identical bricks, shaped as rectangular parallelepipeds, and a measuring tape or a ruler . Your task is to evaluate the length of the inner diagonal of a brick.

Align all the bricks in the same orientation and put them together in an L shape like this:

<code style="margin: 0px; padding: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: var(--ff-mono); font-size: var(--fs-body1); vertical-align: baseline; box-sizing: inherit; background-color: transparent; white-space: inherit; color: var(--black-800); border-radius: 0px;">brick
brickbrick
</code>

Then the body diagonal can be measured in the "missing fourth brick" directly, unobscured by material.
