How many gallons of gasoline are used in
Thailand in one day?
Assume two cars for every three people,
that each car is driven an average of
10,000 mi per year, and that the average
car gets 20 miles per gallon.
Four astronauts are in a spherical space
station. If, as typical, each of them
breathes about 500 cc of air with each
breath, approximately what volume of air
(in cubic meters) do these astronauts
breathe in a year?
What would be the diameter (in meters)
of the space station have to be to contain
all this air?
How many gallons of blood does a human
heart pump during a lifetime?
Estimate that the heart pump 50 cc of
blood with each beat.
1 gallon = 3.788 liters
In Wagner’s opera Das Rheingold, the
goddess Freia is ransomed for a pile of
gold just tall enough and wide enough to
hide her from sight.
Estimate the monetary value of this pile.
The density of gold is 19.3 g/cc, and its
value is about THB 30 per gram.
