Answers:
You will use a minimum of 6 sack mix.
(6-94lb. bags of Air En training Cement per c.m.) = 8 bags for 1&1/4 to 1&1/3 c.m.. Hope this helps you out with your question.
1.2 Cu Meters, I'd order a little extra though.
length X width X height
4 x 3 x .1=1.2 cubic meters.
Jeez, I could do this better if it were in feet and inches.
If it were in feet and inches, it's length time width, divide by 80.
The suppliers would work it out for you as we are a concrete firm
Lemme see 13x10 ft (roughly) =130 sq ft divide x 3 (3x4ins) in 1ft = 40 cu ft 27cu ft = 1 cu metre, If you are using premix concrete order 2cubic yards
