13.6 grams per cubic centimeter. Hint: If you do not know the dimensions of a basketball, you should ESTIMATE
them.

2.
A boxing match occured on a December day that the temperature was 32 degrees, but the
announcers reported that heat would be a problem. Explain why this might be the case.

3.
A professor overheard a bar conversation between two Texans (true
story). One claimed that the 1990 Formula 350 Firebird had a bigger
engine than the 1995 5.7 L Trans Am Firebird because "back then"
they didn't have to worry about fuel economy. The other argued that
Pontiac increased the size from 350 cubic inches to 5.7 L in response to
high sales of the 5.0 L Ford Mustang. Who is right? Do a calculation

The Formula 350 has a bigger engine.

The 5.7 L Trans Am has a bigger engine.

It is impossible to compare the two engines given the information given.

The engines in the two cars are identical.

People should not drive cars with such big engines.
