Answer:
You would need a total of 276 ping pong balls
Step by step explanation:
To determine the number of ping pong balls needed to form an equilateral triangle with 23 rows, we can calculate the total number of balls in the triangle. In an equilateral triangle, each row has one more ball than the previous row. The formula for the sum of the first n natural numbers is given by:
Sum = (n * (n + 1)) / 2
In this case, we want to find the sum of the first 23 natural numbers. Substituting n = 23 into the formula, we get:
Sum = (23 * (23 + 1)) / 2 = 276
Therefore, you would need 276 ping pong balls to arrange them in the shape of an equilateral triangle with 23 rows.
