Check my maths please
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 :D :D 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 :rolleyes: |
Hi Ronnie,
Basically yes! 1000cm3 = 1 litre so 24cm X 17.5cm X 1.8cm = 756cm3 therefore 756cm3 = 0.756 litre Cheers BV. |
I concur, although you missed a 0 from your volume and shouldnt it be mm^3 not mm^2 :D :p
Did the bit you cut off come off in one bit without putting any holes in it? If for a little test, could you not just fill it up with water from a litre bottle and see how much you have left? |
Thanks BV
Not quite as stupid as I thought .... Mind you I did not have a clue as to how to convert square mm into Litres though, had to use an online converter for that :o :o :D :D |

Filling the piece I cut out would be difficult .... Just a flat strip of alloy now :D Thanks Tatey |
My tip is to convert the input units to whatever you would like to get. A litre is a cubic decimetre, so you will get the result in litres if you convert the inputs to decimetres:
2.4 * 1.75 * 0.18 = 0.756 This way you don't have to think about how many cubic millimetres there are in 1 litre. Similarly, if I know a cubic metre of steel weighs 7800 kg, and want to calculate how much a metre length of 25x25x1.5 tube weighs, I convert the lengths to metres: (0.025^2 - (0.025 - 2 * 0.0015)^2) * 1 * 7800 = 1.0998 |

Sounds easy when it is put like that :) |
