Question

we can press a sponge but we are unable to compress a wood block why

Answer 1

It is because sponge has many minute holes in it in which air is trapped so it is compressible while wood block has strong intermolecular attraction and is rigid.
Hope it helps and pls mark as the best answer. :-)

Answer 2

we can press sponge because of the density of it . on the other hand we can't press the wooden block because of high density
