Even in solids there is a small space between the atoms. Depending on how tight the atoms are packed determines the density of matter. This means that a one inch block of wood is not as dense as a one inch block of gold. There is more space between the atoms of the wood than the atoms of the gold.

After 15 years of litigation, Kentucky in 1981 accepted a US Supreme Court decision giving Ohio and Indiana control of at least 100 feet (30 meters) of the Ohio River from the northern shore. This in effect returned Kentucky's border to what it was in 1792, when Kentucky entered the Union. The total boundary length of Kentucky is 1,290 mi (2,076 km). The state's geographic center is in Marion County, 3 mi (5 km) nw of Lebanon.
