Can someone do the math on what the circumference of the earth is?
I did some quick math and I found that it’s at least 120 inches.
Interesting if true

Here’s my methodology. I took my tape measure and laid it flat on the ground in a straight line. My tape measure only goes till 120 inches and it didn’t go around the world. So I concluded that the Earth must be longer than that.

Lmk if you spot any errors in my calculations.
