Sure, let's solve this step-by-step:
1. Understand the conversion factor: We know that 1 pound (lb) is equal to 16 ounces (oz).
2. Given weight in pounds: We are given 3.6 pounds.
3. Set up the multiplication: To find out how many ounces are in 3.6 pounds, we multiply the number of pounds by the number of ounces in one pound.
[tex]\[
3.6 \, \text{lb} \times 16 \, \text{oz/lb}
\][/tex]
4. Perform the multiplication:
[tex]\[
3.6 \times 16 = 57.6 \, \text{oz}
\][/tex]
5. Round to the nearest whole number: We need to round 57.6 ounces to the nearest whole number.
Since 57.6 is closer to 58 than it is to 57, when rounding to the nearest whole number, we get:
[tex]\[
57.6 \approx 58
\][/tex]
Therefore, there are 58 ounces in 3.6 pounds when rounded to the nearest whole number.
[tex]\[
\boxed{58}
\][/tex]
