# Hang Out Inside My Piano!

September 17, 2019

What shape is your house? Maybe a rectangle with some triangle roof shapes?  How cool would it be if it looked like a piano, with a huge violin leaning on it? This cool building was made at the Urban Planning Exhibition Hall in Huainan City, China. The piano has windows all the way around in that stripe, and the violin part holds the stairs that take you inside the piano. You can see how huge a house this is — just look at the tiny people standing at the bottom!

Wee ones: What shapes are the windows going around the piano?

Little kids: The violin has 4 long bars that look like violin strings. If you pluck the first and last to play them, how many strings are left in between?  Bonus: If the 4 violin strings are spaced 2 feet apart, how far is the 4th string from the 1st? Think carefully!

Big kids: Imagine a house shaped like your favorite toy. If it’s 50 feet tall, how much taller than you is it in feet? Or try feet and inches!  Bonus: If that person is 6 feet tall, about how high off the ground is the top of the piano lid? Eyeball it and take a guess!

The sky’s the limit: If the violin part of the building is 60 times as tall as a real violin and 700 inches taller than 10 violins stacked end to end, how tall are a real violin and this violin building?
