Is there a formula for calculating how many litres in a fridge/freeser by measuring the inside lenghtxwidthxheight ?
Then maybe getting cm/inch^2 and changing it to litres?

Thanks

If you are driving a car with the speed of light, what would happen if you turn on the head lights?
Please donot say that you cannot drive at the speed of light or if you drive at the speed of light,you'll be converted in to energy because this can be possible in the coming centuries.

I know this might be silly, but this has been bugging me. I had to do this problem and it looks simple, but I'm lost for words. I might be over looking something, but I just can't seem to figure it out. In the problem I need to subtract 1 from 0.36 which = 0.64

Another way to look at it, as shown in the book is:

1-(0.36) = 0.64

How is this the answer? It doesn't make any sense to me. I know it's the answer because I checked using a calculator, but I want to know how you arrive at this answer step by step. Please help, if anyone knows how you get this answer.
