12. The difference between the upper limit and lowest limit of the

class is called its . . . . . . .. .

13. The length of the side of a cube whose total surface area 600 cm2

is

. . . . . . .

14. Sum of the measures of the exterior angles of any polygon is . . . . .

15. Collection of all the observations is called . . . . . . .​

Answer 1

11. 720

12. The difference between the upper and lower limit of a class interval is called the of the class interval.

13.Total surface area of cube = 600cm

14.the sum of all exterior angles equal 360, allexterior angles are the same, just like interior angles, and one exterior angle plus one interior angle combine to 180 degrees

15.The collection of all the observations is called data.

Answer 2

11.720 degrees

12.class interval

13.600/6

14.180 degrees

15.a collection of observation gathered initially is called Raw data
