Question

what is the approximate length in millimeters of the tissue box (green) as measured by the meter stick?

Explanation:

Step1: Identify scale markings

The ruler has markings for centimeters and millimeters. Each centimeter is divided into 10 equal - parts (millimeters).

Step2: Determine starting and ending points

The tissue box starts at approximately 90 mm (9 cm) and ends at approximately 113 mm (11.3 cm).

Step3: Calculate length

Subtract the starting point from the ending point: $113 - 90=23$ mm.

Answer:

23 mm
