Final answer:
The weight of one block is 25 kg, and there are 625 blocks used to build the wall. The total weight of the wall is the product of the weight of one block and the number of blocks, which is 15625 kg.
Step-by-step explanation:
If a block weighs 5² kg (which is 25 kg), the weight of a wall built with 5´ (which is 625) such blocks can be calculated by multiplying the weight of one block by the number of blocks. To find the weight of the wall, you would perform the following calculation:
- Weight of one block = 5² kg = 25 kg
- Number of blocks in the wall = 5´ = 625
- Total weight of the wall = Weight of one block × Number of blocks
- Total weight of the wall = 25 kg × 625
- Total weight of the wall = 15625 kg
Therefore, the weight of the wall built with 625 blocks, each weighing 25 kg, will be 15625 kg.
