there are 13 girls and 15 boys in the class. Their average height is 161 cm. How many inches do all the students in the class measure together?

1,771.6 inches.

Step-by-step explanation:

As there are 13 girls and 15 boys in the class, there are a total of 28 students (13 + 15). Thus, while the average height of these is 161 cm, the total height in centimeters of all the students is 4.508 centimeters (161 x 28).

Now, 1 centimeter is equal to 0.393 inches. Thus, since 4.508 x 0.393 equals 1,771.6, the height in inches of the entire class measured together is 1,771.6 inches.
