Here’s one way to facilitate this routine.

The Burj Khalifa in Dubai, United Arab Emirates, has been the tallest building in the world since 2009. Its total height is 829.8 meters (2,722 feet), and it weighs approximately 990 million pounds.
Completed in 2009, the construction of the Burj Khalifa began in 2004 and cost about 1.5 billion USD.
If a penny weighs 0.088 ounces, what is the weight ratio of the Burj Khalifa to all the pennies it cost to build it?

On July 9, 2017, Josef Zellner and his friends in Pilsting, Germany, cooked up the largest burger on record, weighing in at 1,164 kg (2,566 lb).
A McDonald's Big Mac weighs 240 grams (8.5 oz) and costs $3.99 in 2021.
If the unit cost of the largest burger made is the same as the Big Mac's, how much would it cost?
63
The Big Rocking Horse, located in Gumeracha, Australia, opened to the public in 1981. It stands 60 feet (18.3 meters) tall.
A toy rocking horse made by labebe™ stands 26.5 inches tall.
If a child with a height of 40 inches can ride this toy, then proportionally, how tall could a "person" be riding on the Big Rocking Horse?
64
The blue whale is the largest animal on the planet, weighing as much as 200 tons and requiring 4 tons of krill each day.
One species of krill, the Antarctic krill, is estimated to number around 400 trillion individuals, each weighing about 2 grams.
How many krill would make up 4 tons?
65
In 2021, the Coca-Cola Company sold over 1.9 billion servings of their drinks each day worldwide, with each serving being 20 ounces.
A standard bathtub holds roughly 80 gallons (302 liters) of water.
How many bathtubs would be filled with Coca-Cola drinks sold every day worldwide?
66
As of September 13, 2021, 178,692,875 people in the United States were fully vaccinated with the COVID-19 vaccine, representing 53.8% of the population.
The vaccines were paid for with taxpayer dollars and provided to all residents, regardless of insurance or immigration status.
Assuming a cost of $20 per dose and that "fully vaccinated" means two doses per person, what is the total cost to vaccinate everyone living in the United States based on the figures above?

Thomas D. Seeley discusses pollen load size in his book, The Wisdom of the Hive. On average, a bee collects about 15 mg of pollen on a single foraging trip.
A colony typically extracts about 20 kg of pollen annually from its environment.
How many trips are made by the bees each year to collect 20 kg of pollen?
68
There are about 10 quadrillion ants alive at any one time, which is about 1 million ants for every human in the world.
Ants are incredibly strong, capable of carrying 50 times their own body weight.
If the average human weighs 140 pounds, how many tons could a human carry if it had the strength of an ant?
69
Saffron is the world's most expensive spice by weight, costing around $5,000 per kilogram. Iran produces about 90% of the world's saffron.
Harvesting saffron is labor-intensive, requiring about 440,000 stigmas and 40 hours of labor to produce 1 kilogram.
If a person works 40 hours per week to harvest 1 kilogram of saffron and is paid $20 per hour, what is the percent markup compared to the cost per kilogram?

Jesse Castenda holds the record for walking the greatest distance of 142 miles and 440 yards in 24 hours, achieved in Albuquerque, New Mexico, on September 18–19, 1976.
A football field measures 120 yards in length.
What was Jesse's walking pace in yards per minute? How many lengths of the football field did he walk?
