Lol, NO ONE got this right... The answer is... ANY AMOUNT OF DIRT from 0 to 72 ft squared, EXCLUDING 72 ft squared, CAN be in the hole. Here's why: The question asks, "How much dirt is there in a hole 3 feet deep, 6 ft long and 4 ft wide?" Technically, you COULD say that "there is/can-be 'x' amount of dirt in a hole that is 3 feet deep, 6 ft long and 4 ft wide". The "x" is the amount of dirt in ft squared. HOWEVER, "x" cannot be 72, because then it wouldn't be a hole.
[This is an "update to the 1st update". If you haven't read the first update, please read that before reading this.] So like I was saying, there CANNOT be 72ft^2 of dirt in the hole,cuz then it wouldn't be a hole. BUT technically, there can be 71.999 ft^2 of dirt in a hole 3 feet deep, 6 ft long and 4 ft wide. In this case though, it would STILL be a hole that has 0.001 ft^2 of empty air left in it. So you can say that there is 71.999 ft2 of dirt in a hole 3 feet deep, 6 ft long and 4 ft wide
