The hole forms a cylinder with radius = 3/2 = 1.5 meters
Hence volume = pi x 1.5 x 1.5 x 9 = 3.1415 x 2.25 x 9 = 63.61 cubic feet
None. It's a HOLE.
None. A hole is the absence of the material.
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
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.
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.
A hole does not have dirt!
The "Great Blue Hole" is 124 metres in depth .

None, All the dirt has been removed from the hole.
None. It's a HOLE.
None. If there was, it would no longer be a hole!

Does air have mass?
None. A hole is the absence of the material.
None! If there was dirt in it then it wouldn't be a hole.
