Well there's hardly any earth in a hole... if you do it properly. Trick question out of the way, if the hole was filled in, it would take 150m3 of dirt
None. It's a HOLE.
2 hours. Because is it takes him 1 hour to dig a hole half the size of what hes going to dig then u have to add another hour to dig 2 more meters long 2 more meters wide and 2 more meters deep.
30 cubic meters
About 2 hours if possible. All you have to do is double everything including the time limit. I disagree. A hole with dimensions of all 2 meters is 8 cubic meters. A whole with all dimensions 4 meters is 64 cubic meters. You aren't just doubling the hole. Yes, you are going twice as deep, but you are also making it a bigger hole. If it took you one hour to dig 8 cubic meters, how many hours will it take you to dig 64 cubic meters? That would be 8 hours.

None. It's a HOLE.
None, All the dirt has been removed from the hole.

Not even close. The hole has a volume of 6 x 10 x 0.5 = 30 cubic meters.
I don't know, but I can tell you there's no earth at all in a HOLE 2 yards long and 4 yards deep.
None. It's a hole. The earth has already been removed. If you remove any more, it's a different size hole.
You cannot answer this question mathematically as you do not know the length of the hole, if it is a square hole (i.e. 1m long) then there was 3m3 of dirt.However if it is a lateral thinking question then the answer is none. It is a hole, therefore it is empty
