EXERCISE The product of \( 1.2 \times 0.6 \times 3.12 \times 0.03 \) is equal to \( \begin{array}{ll}\text { (A) } 0.067392 & \text { (B) } 0.063568 \\ \text { (C) } 0.4812 & \text { (D) } 0.00392\end{array} \)

To find the product of \( 1.2 \times 0.6 \times 3.12 \times 0.03 \), we can calculate it step by step. 1. First, calculate \( 1.2 \times 0.6 \): \[ 1.2 \times 0.6 = 0.72 \] 2. Next, multiply the result by \( 3.12 \): \[ 0.72 \times 3.12 = 2.2464 \] 3. Finally, multiply this result by \( 0.03 \): \[ 2.2464 \times 0.03 = 0.067392 \] Thus, the product \( 1.2 \times 0.6 \times 3.12 \times 0.03 \) is equal to \( 0.067392 \). The answer is \( \boxed{0.067392} \) (option A).
