Step-by-step Solution
To estimate \( 2 \cdot 321 \cdot 8 \) mentally, we can simplify the calculation by rounding the numbers.
First, we can round \( 321 \) to \( 300 \) for easier multiplication:
\[
2 \cdot 300 \cdot 8
\]
Now, we can calculate this step by step:
1. Calculate \( 2 \cdot 300 = 600 \).
2. Then, multiply \( 600 \cdot 8 \):
\[
600 \cdot 8 = 4800
\]
Thus, the estimated value of \( 2 \cdot 321 \cdot 8 \) is approximately \( 4800 \).
The closest answer choice is:
**D. 4800**
Quick Answer
The estimated value is approximately 4800.
