I have a board 55 inches long, and 12, 4 inch balls, how far apart do I space them?
To determine how far apart to space the 12 balls on a 55-inch board, you can follow these steps:
1. Determine the space needed for each ball: Since you have 12 balls and a 55-inch board, subtract the combined diameter of the 12 balls from the length of the board. Each ball has a diameter of 4 inches, so their combined diameter is 12 balls multiplied by 4 inches, which equals 48 inches.
Length available for spacing = Length of the board - Combined diameter of the balls
= 55 inches - 48 inches
= 7 inches
2. Calculate the spacing between each ball: Divide the available length for spacing by the number of gaps between the balls. Since you have 12 balls, there will be 11 gaps between them.
Spacing between each ball = Length available for spacing / Number of gaps
= 7 inches / 11 gaps
≈ 0.64 inches (rounded to two decimal places)
Therefore, each ball should be spaced approximately 0.64 inches apart from one another on the 55-inch board.
