Calculating the Day of the Week

To determine the day of the week when the last piece is cut, we can use the concept of modular arithmetic and the fact that there are 7 days in a week.

1. Calculating the Day of the Week - We start with Monday as the first day of the week, so it has a value of 1. - Since 400 meters are cut into 5 equal pieces of 80 meters each, we can calculate the day of the week when the last piece is cut.

2. Using Modular Arithmetic - We can use modular arithmetic to find the day of the week when the last piece is cut. The remainder when dividing the total length of the wire by the length of each piece will give us the day of the week.

3. Applying the Calculation - We can apply the calculation to find the day of the week when the last piece is cut based on the information provided.

Calculation

To calculate the day of the week when the last piece is cut, we can use the following formula:

Day of the week = (First day of cutting + (Number of pieces - 1)) mod 7

Given that the first piece is cut on Monday (which corresponds to 1 in our calculation), and there are 5 pieces in total, we can calculate the day of the week when the last piece is cut.

Result

Using the formula, we can calculate the day of the week when the last piece is cut.

Day of the week = (1 + (5 - 1)) mod 7

Day of the week = 5

So, the last piece will be cut on Friday.
