Good Morning Mates,
I trust you all had a good nights sleep.
I hope you have your thinking caps on this morning as we are about to figure some concrete for a patio.
The patio is going to be 3.65M x 4.87M x 101.6mm.
How many cubic metres of concrete will it take to pour and finish it?
I do know the answer as I first figured it out in feet and inches and then converted to your metric system.
Respectfully, :)

In round figures, 2 cubic metres...and there's a bit left over to pour the barbeque slab that's boxed up in case there's a bit left over.

Imperial - Assuming original size is 12' x 16' x 4"
convert inches to feet 12' x 16' x .333' = 63.994 cubic feet
convert cubic feet to cubic yards (divide by 27) = 2.37 cubic yards
Allow 10% for safety = approx 2.6 cubic yards
Metric - 3.65 x 4.87 x .1016 = 1.806 cubic metres
Allow 10% for safety = approx 2 cubic metres..
You can reduce quantity by about 1 cubic metre for each disposed dead body in the mix although concrete slabs tend to be not as efficient at hiding bodies as much as larger concrete support type structures...

if you're going to bury a body in a 4" thick slab I think you're going to have to steam roller it flat first ......

Hello Mates,
Though I know it is only a little after noon down there it is 10:00 PM here so here is the answer for the quiz;
As already mentioned it is not a woodworking quiz but a construction quiz and you are correct as the answer is 2 cubic metres.
Tomorrows quiz will definitely be a woodworking quiz.
Thanks for your support.
Respectfully, :)

Well I didn't look at the other answers first but worked out the answer as being EXACTLY 1.8059908 cubic metres
Now I've just got to find a concrete company with accurate measuring equipment. :)

I would like to know where you would get a concreter that would lay a slab 101.6mm thick.:D

My concretor laid a slab 101.6mm thick, also 123.85 mm thick, also 94.2mm thick also......... :mad:
Now do you want to know how deep the puddles were?? :(
Thanks to the miracle of modern grinders and epoxies, it's now level, and 111.6mm thick! :)
cheers,

OK. so what epoxy stuff did you use?
I have some concrete that unfortunatly slopes towards the house, instead of away, and I would like to fill the puddle, only prob is, its coloured concrete.
