7600mm long x 250mm width x 450mm deep
and
8900mm long x 150mm width x 300mm deep.

How many cubic metres of ballast do I need for my footings
Thanks

Convert your measurements to metres then multiply

7.6 x 0.25 x0.45
8.9 x 0.15 x 0.3

I know a constipated Mathematician. He always works it out with a pencil.

As Hailsham Seagull has already said, approx 1.26 cu m. should be enough. However I always add at least 10% to allow for irregularities in the depth/width of the trench.
Also, they are very narrow footings, what widths are the walls you are building?

I was thinking that, very narrow and not very deep.
Plus, where do you buy a shovel 150mm wide unless its a kiddies bucket and spade from the beach.

Always order more if it's raining.

Do your own homework cheats never prosper.

don't forget to add cement and water to the ballast or it will not harden

My mate Pat suggests turning your shovel sideways

Try one of the post hole spade, they are skinnier than the normal shovel/spade.
