Question
Alma's shoebox is 20 centimeters long and 10 centimeters wide. The length of the shoebox ____________ millimeters more than its width.
- 100
- 200
- 200
- 300
Hint:
cm = centimeter
mm = millimeter
1cm = 10 mm
Subtract the width from length
The correct answer is: 100
Length of shoebox is 20cm
In millimeters, 20 × 10 = 200mm
Wide of shoebox is 10cm
In millimeters, 10 × 10 = 100mm
So, here the length is 200 – 100 = 100mm more than width.
Subtract the width from length and convert cm into mm
