hello again i have to re-post as i couldnt update my last one.
i need a shed floor doing dimensions 8x6foot x2.2inch i have already put membrane down and gravel on top of that. i have looked around for materials and how much on i would need on the and this was my results.
Results:
8.80 cubic feet or 0.326 cubic yards or 0.249 cubic meters
if pre-mixed concrete*, it is 1.17e+3 lbs or 531 kgs
if 60 lbs per bag, it is 19.5 bags
if 80 lbs per bag, it is 14.6 bags
which means i need atleast 531kg of material. since finding that and doing research i have found that the mix is 4 sand and 1 cement. which would mean that 5 bags(25kg) of and 20 bags (25kg) of sharp sand total 625kg.
should be plenty the cost of this is £38.15 from B&Q.
so that's £38.15 material cost.
someone make me a good offer. it really should take too long an hour or two at most.
