Hang on a minute!.... a 50 x 50 x 50cm pot is not half a cubic metre ... it's one eighth of a cubic metre. If only hubby had asked me (I'm the one attempting the maths at present) before he ordered all that dirt! We now have a ridiculously enormous pile of dirt at our front gate (which never seemed to get smaller the more we dug), waiting to greet our visitors on Christmas Day. Half of it will end up in my house for sure! Our neighbour thinks we are the best - free topsoil. The rest?..... 400 trips with a bucket up 24 steps on Boxing Day, to topdress the top lawn. Aren't we a learned pair... can't even work out cubic metres.... some scientists! See kids, do your Maths.. it does come in handy when you are a grown-up. LOVE learning from mistakes!... and I can't lift my arms!... or move my neck!
