Yes, I'd make that out to be around 11.14 m3 which is roughly the same.

Order 12 m3 and you cant go wrong. Better looking at it than looking for it

When I converted to m before multiplying I got 11.16 but when I converted after getting the cubic foot measurement it came out to more... hmmm.

Aye, I was using 0.15 as a conversion of 6" and that's where the difference probably is. Should have used 0.152. You are indeed correct at 11.32 m3

It puzzed me a little so I did it both ways and it worked out the same:

40 x .3048 = 12.192
20 x .3048 = 6.096
0.5 x .3048 = 0.1524

12.192 x 6.096 x 0.1524 = 11.326


40 x 20 x 0.5 = 400.
400 x .0283 = 11.32
