Question

A compound has the formula C8H8 and does not contain any double or triple bonds. All the carbon atoms are chemically identical and all the hydrogen atoms are chemically identical. Draw a Lewis structure for this molecule. Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons.

Explanation / Answer

Cubane, C8H8

It "sorta" looks like this.
....H.........H
............../
H.....C - C  
...../.|.../.|
....C - C.C- H
.... |.....|./
....C - C
.../.........
H............H

Imagine a cube of carbon atoms, with a single hydrogen attached at each of the 8 corners. That way we have complete symmetry, since all of the bonds, carbons and hydrogens have the identical environment as per your request.
========= Follow up ==========

Cyclooctane is C8H16 .... too many hydrogen atoms. The other suggestions by Plays_poorly turn out be C8H16 as well.
