Answer:
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.
Draw a right triangle (attachment below):
Length of the vertical line = 6 units
Length of horizontal line = 8 units
a^2 + b^2 = c^2
6^2 + 8^2 = 100
Square root of 100 = 10
The distance between the two points is 10 units.
