Question 1

How much would it cost to cover a football field with one-dollar bills?

Accepted Answer

$$\begin{array} { l } 
A _ { \text {field } } = \left( 50 y d s ^ { \times } 120 y d s \right) \left( \frac { 36 \mathrm { in } } { 1 y d } \right) = 216000 \mathrm { in } ^ { 2 } \
A _ { \text {bill } } \approx ( 2 \mathrm { in } \times 6 \mathrm { in } ) = 12 \mathrm { in } ^ { 2 } \
\frac { 216000 in ^ { 2 } } { 12 \text { in } ^ { 2 } / \$ } \approx \$ 18,000 \
