Calculating Remaining Fabric

To calculate the total remaining fabric, we can simply multiply the number of pieces of each type of fabric by their respective lengths and then sum the results.

- There are 20 pieces of fabric measuring 40 meters each. - There are 12 pieces of fabric measuring 30 meters each. - There are 13 pieces of fabric measuring 20 meters each.

Calculation

To find the total remaining fabric, we can use the following calculation:

Total remaining fabric = (20 * 40) + (12 * 30) + (13 * 20)

Result

By performing the calculation, we find that the total remaining fabric on the warehouse is:

940 meters
