Answer 2

We should know the height to know the average chest size of a 20-year-old boy.

Explanation:

• We need to know the height with the age to measure the average chest size. Because chest size not only depends on age, it also depends on height and other things.

• For example, if age is 20 and height is 145 cm (or) 4’ 10” Ft then average chest size is 28.5 (in Inches).
• If age is 20 and height is 150 cm (or) 5’ 0” Ft then the average chest size is 29.5 (in Inches).
• If age is 20 and height is 162.5 cm (or) 5’ 5” Ft then average chest size is 31 (in Inches).
• If age is 20 and height is 180 cm (or) 6’ 0” Ft then the average chest size is 33 (in Inches).
