What is the answer to this general-geek-knowledge based multiplication problem.
For purposes of clarity all numbers should be rounded to the nearest integer
before multiplying them. The sum of any two opposite sides on a 6-sided die * Smallest prime number greater then a dozen * # of decimeters in a meter * # of days in the 2100AD calendar year * # of planets closer to the Sun then the Earth * # of US Dollars represented by a bill with Lincoln’s face on it * # of “permanent” Security Council members in the UN * # of thirds of the Earth’s surface covered by ocean * Pi * Acceleration of gravity at sea-level in meter/sec/sec = ? |

Solution: |
Sum of opposite sides of a 6-sided die = 7 Smallest prime number greater then a dozen = 13 # of decimeters in a meter = 10 # of days in the 2100AD calendar year = 365 (not a leap year because of the 100 year rule) # of planets closer to the Sun then the Earth = 2 (Mercury & Venus) # of US Dollars represented by a bill with Lincoln’s face on it = 5 # of “permanent” Security Council members in the UN = 5 (China, France, Russia, UK, and US) # of thirds of the Earth’s surface covered by ocean = 2 (71% is ocean) Pi rounded to one digit = 3 Acceleration of gravity at sea-level rounded to the nearest meter/sec/sec = 10 Product = 996450000 |
