How many bags of readymix concrete would I need to fill a volume of approximately 0.25 cubic yards.
Google tells me
0.25 (cubic yard) = 191.138714 litresWhich I thought might help.
But then I see concrete (ready mixed) is in 20kg bags.
and this page says
which means 1/4 x 110?
= about 27
Which sounds a huge amount.
What have I done wrong?
