"It is physically impossible to exceed the 70-pound domestic weight limit for a small flat rate box.
"The interior dimensions (8 5/8" x 5 3/8" x 1 5/8") are ~75.333 in^3.
"If you filled the box with pure osmium, the densest substance known to man, it would weigh ~61.48 lbs.
"Should have said densest substance on Earth. Fill it with neutron star and you'll be approx. 30 trillion kg overweight.
