Answer :

Sure, let's go through this step by step to solve the problem.

### Step-by-Step Solution:

1. Understanding the Problem:
We are given two numbers, 10 and 4, and we need to find the result of multiplying them. The context of this multiplication is not provided, but our primary task is to perform the arithmetic operation.

2. Identifying the Numbers:
- The first number is 10.
- The second number is 4.

3. Performing the Multiplication:
To find the product, we multiply the two numbers together.
[tex]\[ 10 \times 4 \][/tex]

4. Calculating the Result:
The multiplication of 10 by 4 is calculated as follows:
[tex]\[ 10 \times 4 = 40 \][/tex]

5. Conclusion:
The result of multiplying 10 by 4 is 40. This means that when you take 10 and multiply it by 4, you get a product of 40.

So the solution to the question about the maximum pressure it exerts on the duron is:
[tex]\[ 10 \times 4 = 40 \][/tex]
Hence, the maximum pressure is 40 units.
