LMAO i fucked up soo hard on that one.

Thought it had 150k km in OP and I meant earth is 40k km long.
So messed up there.

Incorrect I guess? : p


REAL ANSWER =

60.000.000.000 cubic meters
= 60000000000 cubic meters

phew ... I was starting to lose faith in saudi arabia

 

Real answer =

2,118,880,003,289.315 cubic feet or 78,477,037,158.864 cubic yards or 60,000,000,000 cubic meters.
If pre-mixed concrete*, it is 281,811,040,437,478.875 lbs or 127,800,000,000,000 kgs.
If 60 lbs per bag, it is 4,696,850,673,957.981 bags.
If 80 lbs per bag, it is 3,522,638,005,468.486 bags.

 

Hold the fucking phone.

Meters are length and cubic meters are volume, right? So, logically, the only way to get from meters to cubic meters is to apply the formula for volume, which is Length * Width * Height.

This would give us 60,000,000,000 meters, which would be 20,000,000,000 cubic meters.

Right?

I don't know what confusion of ideas leads you to divide by 3 but both of these are incorrect.

At the equator... dry lake bed... sea level... constant temp and pressure... does not expand or contract much...


I'm failing to see why it would not just be LxHxW as it is suppose to be solid, the conditions are ideal, and don't need to worry about structural integrity nor wind nor Earth's rotation.


unless the answer is 0 as it can't hold itself up without assistance, unless magical communist concrete proves me wrong again

0 is incorrect.

0 is incorrect.

damn magic communist concrete

This answer is still incorrect even after being repeated for the 10th time.

Can't be sea level

There is no reason you cannot have a dry lake at sea level.

2,118,880,003,289.315 cubic feet or 78,477,037,158.864 cubic yards or 60,000,000,000 cubic meters.

Incorrect.

 

Doesn't constant standard temperature mean it will stay in liquid form?
So won't harden.

Also how are you gonna build a 2 KM high wall ?

 

[I Am Hunter]

Magic communist concrete withstands pressure far beyond any other concrete... it seems to defy everything, thus it must also be able to build itself from nothing

Cement sets via a chemical reaction between the cement powder and the water molecules. It does not set from heating.

 

[I Am Hunter]

It is to be assumed that this can be made without collapsing or crushing itself under its own weight?


If this does not have a 'trick' answer of sorts I am beyond puzzled


I'd have to say that the wall just cannot be made that tall as concrete is not strong enough to withstand that much pressure. RIP Jim's fam

 

60.000.000.000 cubic meters. x 0.58% ? So 34.800.000.000 cubic meters.
Since you need about 42% water according to Wikipedia.

It is magic communist concrete, it needs the tears of orphans, not water. Also, must be 69% ToO (Tears of Orphans)


Also, also, there are a lot of different concrete types with varying water to concrete mix mixtures.

If the cement has the same volume dry and wet then you don't need to factor water into it do you. Cement is not the problem. If you want to build a structure that is X cubic meters in volume you order X cubic meters of this special cement.

 

If the cement has the same volume dry and wet then you don't need to factor water into it do you.

Well cement doesn't become concrete unless you add water : p
So you just throw away a bunch of cement and add water to turn cement into concrete.

The question asks how much concrete is needed. This is already mixed and ready to go.

 

Jim is an engineer in an equatorial communist society. His boss requires that he build a wall across a dry lake bed at sea level. If he gets it wrong his fam is done for.

The wall is to be 150,000 m long, 200 m wide and 2000 m high. The wall is to be made from special concrete that has the same density (and volume) when dry as when wet and does not expand substantially when heated. The wall is to be solid and all one piece.

Help Jim out: Assuming constant standard temperature and pressure for the build how many cubic meters of concrete does Jim need?

Too much concrete, he should just get a different job

His boss requires he builds a wall across a dry lake bed at sea level, so basically its 200x150000x2000 "lake"
sounds like a river bed instead m8
sea level doesnt matter as he has to make the wall to the figures above

I just get the same answers as others lol 60,000,000,000 cubic meters

Guess his fam will be shot

Well... I'm sticking with this, if it is idealized as much as this and it is not just LxWxH to find how much concrete is needed to order, maybe I'm overlooking something but I gotta gib up

 

[Accounts Shop]

he needs 90'344'133'429'000 kg of hitler cement

 

60009407190 m^3

 

Jim failed to calculate the needed concrete volume for the wall and his family was shot.

Jim believed erroneously that he was building on a flat plane when in fact he was building on the surface of a sphere. Taking into account the curvature of the earth at the equator Jim needed an additional 9.4 million cubic meters of concrete to complete his wall.

Bad luck Jim


Edit: Meteor got it just seconds before I posted. Cool kid minirank incoming. Jim survived. Let's find out what else he can survive on the next installment of Sythe Users: What Do They Know? Do They Know Things?? Let's Find Out!
