Question

a stack of cards is placed next to a ruler, and the height of stack measured to be 3/4inches. how thick is one card

Answer 1

Total thickness of the stack of cards = 3/4 inch or 0.75 inch

In a full stack of cards, there are 52 cards.

Hence, the thickness of 52 cards = 0.75 inch.

To find the thickness of one card, we divide the total thickness with the total number of cards.

Thickness of one card =
`(0.75)/(52) = 0.014423 inch`

1 inch = 2.54 cm

0.014423 inch is approximately equal to 0.34 cm.

Answer = 0.34 cm
