I am trying to work out how much muck I am going to get if I excavate an area 5M wide X 3M long X 200mm deep. so I started by multiply the 5 by 3 and got 15 M Sq and then multiplied by .2 to get 3 cubic Meters.... is this right?

Sounds right but don't forget that if you have to remove it from site (unless you have time to ram it into a skip) you must add a bulk up factor of about 2.5 depending on the precise nature of the ground.
I screwed up badly once with the cost of grab lorries because of this.

you will get around 6-7 tons depend on the material being dug out, should all go in a 8 yard skip MSH

Technically yes but once excavated the volume will increase by anything from 1.3 to 1.6 times depending on the type of excavated material. This is only a guideline and can vary enormously if you add concrete etc into the equation. If it's normal earth multiply the solid cubic m by 1.5 and you'll get the close to the amount you'll end up with. If you're filling skips then layer it and foot stamp and you'll make it go a lot further. It should weigh approx 6.5 ton. These are all guesstimates and depending where you are and what you will be shifting could be way off.

i normally just times by 2,so a 3 m3 hole fills a 6m skip
