Question

Maggie stacked a box that was 83 centimeters (cm) tall on top of a box that was 128 centimeters. How tall was the stack of boxes in meters and centimeters?

Answer 1

The height of the stack is given by the sum of the heights of the boxes:

$83\text{ cm}+128\text{ cm} = 211\text{ cm}$

In order to convert this result in meter, remember that

$1 \text{ m} = 100\text{ cm} \implies 1 \text{ cm} = 0.01 \text{ m}$

So, to covert form centimeters to meters we have to multiply by 0.01 (or divide by 100).

Which means that

$211 \text{ cm} = 2.11 \text{ m}$
