You won the lottery and you want to give 5.00 million dollars to the animal shelter, by leaving it on its door step.
a. (Use Dimensional analysis , significant figures, scientific notation and re-write the answer using prefixes.) How heavy is the bag(s) with the 5.00 million dollars, assuming the bag weight is negligible and that you only used 100dll bills? (one 100 dll bill = 1.00 gram).
b. (Dimensional analysis) What is the volume all of the bills would occupy. Every bill is the size of 155.81mm x 66.42mm X 0.10 mm. (1 mm3 = 1 x 10-9 m3 and 1L =0.001m3) Volume = Length * Height * Width, or V = L * H * W. Express the answer in liters
c. (density) Assuming it all fit in one bag, how dense would that bag be?
