The number of such rooms that a billion 1- dollar bills would fit

Question

A 1-dollar bill is 6.14 inches long, 2.61 inches wide, and 0.0043 inch thick.
Assume your classroom measures 27 by 24 by 14 ft.

Answer 1

First, convert the rooms dimensions from feet to inches. 

 

(27×12)×(24×12)×(14×12)

324×288×168=15,676,416 cubic inches

 

Now, determine the volume of one dollar bill

 

6.14×2.61×0.0043= 0.06890922 cubic inch

 

Multiply the bill's volume by 1 billion to determine how much volume they all have, then divide that number by the room's volume to find how many rooms it will take.
