**Revised on July 12, 2023**

During past years author worked with **block-wise**, **bordered** and **block-bordered** magic squares. This work make connection between **block-wise** and **bordered** magic squares. We started with **block-wise bordered** magic squares of orders 120 and 110. Based on these two big magic inner order magic squares multiples of 10 are studied. By inner orders we understand that magic squares of orders 90, 80, 70, etc. The construction of the **block-wise bordered** magic squares multiples of 10 is based on **equal sum blocks** of magic squares of order 10. We have taken **14-types of magic squares of order 10**. The advantage in studying **block-wise bordered** magic squares is that when we remove external border, still we are left with magic squares with sequential entries. It is the same property of **bordered** magic squares with single digits. The difference is that instead of numbers here we have blocks of equal sum magic squares of order 10. For multiples of orders 4, 6 and 8 see the links below:

1. Block-Wise Bordered and Pandiagonal Magic Squares Multiples of 4.

2. Block-Wise Bordered Magic Squares Multiples of Magic Squares of Order 6.

3. Block-Wise Bordered and Pandiagonal Magic Squares Multiples of 8 – Revised

The further multiples, such as multiples of 12, 14, 16 etc. shall be written soon. This work is up to order 120. Examples below are only up to order 40. The higher order examples can be seen in Excel file attached at the end of this work. This work also can be seen as online:
