Calculating the Total Length of Ribbons

To calculate the total length of ribbons Cinderella prepared for the ball, we can use the following steps:

1. Calculate the Length of Blue Ribbons: - Cinderella prepared 3 blue ribbons, and each ribbon is 3 meters long. - Therefore, the total length of the blue ribbons is 3 (ribbons) * 3 (meters/ribbon) = 9 meters.

2. Calculate the Length of Pink Ribbons: - Cinderella prepared 7 pink ribbons, and each ribbon is 3 meters long. - Therefore, the total length of the pink ribbons is 7 (ribbons) * 3 (meters/ribbon) = 21 meters.

3. Calculate the Total Length of Ribbons: - To find the total length of all the ribbons, we add the lengths of the blue and pink ribbons together. - Total length = 9 meters (blue ribbons) + 21 meters (pink ribbons) = 30 meters.

Therefore, Cinderella prepared a total of 30 meters of ribbons for the ball.
