How deep does water have to be to float a houseboat that is 12 x 36 and about 10000 pounds dry weight?

To float a houseboat that weighs 10,000 pounds, it needs to displace an equivalent weight of water. Since freshwater weighs approximately 62.4 pounds per cubic foot, the boat must displace about 160 cubic feet of water to float. Given the dimensions of the houseboat (12 x 36 feet), it would require a minimum water depth of about 4.5 feet (36 feet divided by 8 feet of width) to ensure it floats properly without risk of grounding. However, a deeper water depth is recommended to accommodate waves and movement.
