d) If a stack of ten 3.5 inch diskettes is measured to 34 millimeters high, and each disk has a mass of approximately 2.34 grams, how many kilograms would a stack of disks 12.34m high be?
10 diskettes=34mm=0.34cm=23.4g
1 diskette=2.34g
new height=12.34m=1234cm
(Answer: how many diskettes will fit x 2.34g)
(disk height)# of disks in new height=1234cm/0.034cm=36,000 (w/ sig figs)
# of disks x 2.34g=weight of new height=84,240g=84.24kg
