Check my maths please

[Bonzo]

Would any of you maths boffins out there be kind enough to double check my calculations for me

Not my strongest of subjects at school .... Too busy winding up the teachers & showing off to girls

The section of sump I recently removed was approximately: 240mm long X 175mm wide 18mm deep.

I worked this out to 75600 mm2

This in turn coverts into .756 litres lost oil capacity ( 3/4 L ) Right !!??

Personally would have guessed about 1/2 litre .... Perhaps i'll have to provide some extra capacity after all
