The Tallest Lego Tower Ever

February 22, 2017

Someone is always building big new things out of Lego, and this Lego record is an exciting one: the world’s tallest Lego tower. Built in Budapest, Hungary out of 450,000 bricks, it stands 114 feet tall! The “official” Lego builders clipped on metal cables that run to the ground to keep the whole thing from tipping over. They even topped it with a Rubik’s Cube, the famous 3x3x3 colorful cube toy, since inventor Erno Rubik is Hungarian. A Lego brick is less than half an inch tall, so you can imagine how many layers this tower must have. See how high your own Lego can go!

Wee ones: If the tower uses blue, red, green, white and yellow bricks, how many colors is that?

Little kids: If you’re in charge of adding 70 bricks onto the tower, and you’re counting the bricks by 10s, what numbers do you say?  Bonus: The tower was finished on a Wednesday and stood for only 5 days. On what day was it taken down?

Big kids: 8 layers of bricks stack 3 inches tall. How many layers stack to 1 foot? (Reminder: A foot has 12 inches.)  Bonus: If the 450,000-brick tower uses 5 colors equally, how many bricks of each color does it use?

 

 

 

Answers:
Wee ones: 5 colors.

Little kids: 10, 20, 30, 40, 50, 60, 70.  Bonus: The following Monday.

Big kids: 32 layers.  Bonus: 90,000 bricks of each color.
