# A deck of 52 playing cards is about 3 quarters of an inch thick. What is the thickness of each card in millimetres?

this is a question about measurements more specifically conversion between two units of measurement.

It isn't. A deck of 52 playing cards is NOT three quarters of an inch thick. It's only about half an inch thick. EVER.

Sorry. You failed to take two things into consideration: first, the premise is flawed. A deck of playing cards is only ever about half an inch thick. Ever. Second, the thickness of the deck is stated to be "about", approximate. Therefore, you have just led the reader to calculate a precise answer to an approximate question, the answer therefore being a bad msmatch.

Sorry. You failed to take two things into consideration: first, the premise is flawed. A deck of playing cards is only ever about half an inch thick. Ever. Second, the thickness of the deck is stated to be "about", approximate. Therefore, your calculated thickness should be likewise approximate instead of accurate to <0.1%.

Second, the thickness of the deck is stated to be "about", approximate. Therefore, you have just stepped through an overcomplicated, convoluted process to reach an inordinately precise answer, which should have been only approximate.
