Problem Analysis

To determine if 12 sheets of cardboard are enough to make 72 book covers, we need to calculate the number of book covers that can be made from each sheet of cardboard. Then we can multiply that number by 12 to see if it equals or exceeds 72.

Solution

1. Calculate the number of book covers that can be made from each sheet of cardboard. 2. Multiply the result from step 1 by 12 to get the total number of book covers that can be made from 12 sheets of cardboard. 3. Compare the result from step 2 with 72 to determine if it is enough.

Calculation

To calculate the number of book covers that can be made from each sheet of cardboard, we divide the total number of book covers (72) by the number of sheets used for 6 book covers (6).

Number of book covers per sheet = 72 / 6 = 12

Now, we multiply the number of book covers per sheet by the number of sheets available (12) to get the total number of book covers that can be made.

Total number of book covers = 12 x 12 = 144

Answer

Based on the calculations, with 12 sheets of cardboard, you can make a total of 144 book covers. Therefore, it is more than enough to make 72 book covers.

Please note that the calculations assume that each sheet of cardboard can be used to make the same number of book covers.
