Subtract 8 from 48: Base-10 Block Visualization Problem

To solve this problem, we'll perform a simple arithmetic subtraction, as follows:

• Step 1: Identify the initial number of units, which is 48.
• Step 2: Identify the number of units to subtract, which is 8.
• Step 3: Perform the subtraction $48 - 8$.

Let's carry out the calculation:
Step 1: We start with a total of 48 units.
Step 2: We subtract 8 units from 48.
Step 3: Calculating the subtraction, we find:
