Well, if a 20-bushel hamper is 48×32x30 (length, width, height) then the volume in inches in 46,080. You will have to measure the size of the velour to see if it can fit into the box. Or, if you have both the hamper & velour, just stuff it in & see if it fits. If not, have a bunch of kids jump on the lid, like it’s an airport luggage suitcase.
