I have 432 cards that are three and a half inches long if I put them end to end how many feet long is the line of cards

432*3.5 is the total length in inches.

12 inches = 1 foot.
Can you take it from here?

432 * ( 3 1 / 2 ) = 432 * 3.5 = 1512 in

1 ft = 12 in

1512 / 12 = 126 ft

To find out how long the line of cards would be in feet, we need to convert the length of the cards from inches to feet. Since there are 12 inches in a foot, we can use this conversion factor.

First, let's determine the total length of the line of cards in inches. We'll multiply the number of cards (432) by the length of each card (3.5 inches):

Total length in inches = 432 cards * 3.5 inches = 1512 inches

Now, let's convert the length from inches to feet. We'll divide the total length in inches by 12:

Total length in feet = 1512 inches / 12 = 126 feet

Therefore, if you put the 432 cards end to end, the line of cards would be 126 feet long.
