Titanic was a British passenger liner that sank on April 15, 1912. This was one of the most famous tragedies in modern history. Titanic was 882.5 ft long, 92.5 ft at its widest, and 104 ft high.

Situated in Williamstown, Kentucky, Ark Encounter is the largest timber frame structure in the world. It's built according to the dimensions given in the Bible. It's 510 ft long, 85 ft wide, and 51 ft high.

Let's regard these dimensions as those of rectangular prisms, what is the volume of Titanic to Ark Encounter?

Published between 1932 and 1946, in 27 volumes, Les Hommes de bonne volonté (Men of Good Will) by French author Jules Romains is considered one of the longest novels, per word count, ever published through a mainstream publisher. The book has 2,070,000 words.

An adult can read around 250 words per minute.

The Lockheed SR-71 Blackbird is the fastest jet on the planet and made a record-breaking time flying from Los Angeles to Washington D.C. in 64 minutes and 20 seconds.

A regular passenger airplane can make the same flight path in 4.5 hours.

The flight distance between Los Angeles and Washington D.C. is 2,280 miles. What was the Blackbird's average speed when it made the record-breaking time above? Round your answer to the hundredths place.

Chateau Grand Traverse shares these facts on its website:

• 1 acre of grapes contains approximately 1075 vines.
• 1 vine contains approximately 30-40 clusters.
• 1 cluster contains about 130 grapes
• 8,000 grape clusters/ton
• 1 ton yields approximately 170 gallons of finished juice
• 1 case contains 2.37753 gallons, which yields about 72 cases or 864 bottles, which means it takes approximately 111 clusters to yield a case or 9.25 clusters/bottle

How many grapes are needed to make one bottle of wine?

Diamonds are valued according to their cut, color, carat and clarity. It's expensive because the average yield in most diamond mines is 1 part diamond to 1 million parts host rock. Diamond is the hardest natural substance that can only be scratched by another diamond. One carat costs anywhere between $2,500 and $16,000.

In 2007, the Harvard-Smithsonian Center for Astrophysics announced the discovery of a 10 billion-trillion-trillion carat diamond in the sky called Lucy. The star is located fifty light years from Earth.

​Write "10 billion-trillion-trillion" in scientific notation.

The Challenger Deep in the Mariana Trench is the deepest known point in Earth's oceans. Its depth is at 10,994 meters (36,070 feet) below sea level.

​Mount Everest is Earth's highest mountain above sea level with an elevation of 8,848 meters (29,029 feet). It's located in the Mahalangur Himal sub-range of the Himalayas. 

​Say an adult human stands 6 feet tall. How many adults would it take to stack from the Challenger Deep to the top of Mount Everest?

The Dead Sea is a landlocked salt lake between Israel and Jordan. It is at 418 m below sea level, therefore its shores mark Earth's lowest point not under water. Due to the lake's high salt content, you can float in it. The salt concentration of the Dead Sea fluctuates around 32%. 

An average bathtub can hold 300 kg of water. The volume of the Dead Sea is 114 km^3 (27 cu mi). 

How much salt is needed to turn a bathtub into a mini Dead Sea? How many tons of salt are in the Dead Sea?

In his book "Outliers," best-selling author Malcolm Gladwell popularized that it takes 10,000 hours of practice to be great at something. 

Herbert Simon and William Chase wrote a paper in American Scientist that to reach the grandmaster level in the game of chess, one might need to spend as many as 50,000 hours staring at chess positions. 
 
Say, you're 5 years old and wanted to put in 50,000 hours to become a grandmaster at chess. But you can only spend 4 hours each day doing so. How old will you be by the time you've reached your goal?

Octopuses live in the ocean and are famous for having eight arms. Octopuses lay 56,000 eggs at a time.

An ostrich can lay 10 eggs at a time, each egg weighing as much as 1.5 kg. 

Let's say that each octopus egg weighs as much as one grain of rice, which is 0.029 g. What is the weight ratio of ostrich egg to octopus egg?
