Answer 2

Calculation of Paper Used for Each Snowflake

To calculate the amount of paper used for each snowflake, we need to determine the total number of snowflakes made and the total amount of paper used.

According to the information provided, the 3-a class made 64 identical snowflakes, while the 3-b class made 72 identical snowflakes. In total, there were 64 + 72 = 136 snowflakes made.

The total amount of paper used for all the snowflakes was 408 dm. To find out how much paper was used for each snowflake, we divide the total amount of paper by the number of snowflakes:

408 dm / 136 snowflakes = 3 dm of paper per snowflake.

Therefore, each snowflake required 3 dm of paper.
