ok...
u have built an exact replica of ur favorite sailboat on a scale of 1 to 20. u know that the boat weighs 3050 kg. to wat total weight, in grams, would u have 2 ballast the model so it floats in water like the real thing?
i thot it would just b 3050/x = 20/1
then x = 152.5 kg
but...thats not the rite answer...as per usual...
ne1 want to help me get started on this 1?
