Question

A stack of 250 cards are placed next to a ruler, and the height of the stack is measured to be 5/8 inches. How thick is one card?

Answer 1

The thickness of 1 card = 0.0025 inches

Explanation:

Here, the total number of cards in the stack = 250 cards

The total height of the stack = 5/8 inch = 0.625 in.

`\textrm{Thickness of one card} = \frac{\textrm{The total thickness of the stack}}{\textrm{The total cards in the stack}}`

`\implies \textrm{Thickness of one card} =(0.625)/(250) = 0.0025`

Hence, the thickness of 1 card = 0.0025 inches
