Question

The height of a cupboard drawer is 35 cm. Three boxes measuring 3 cm 3 mm, 2 cm 5 mm, and 4 cm 5 mm in height are placed one on top of the other in the drawer. How much space is left above the boxes in the drawer

Answer 1

3 cm 3 mm = 3.3 cm, 2 cm 5 mm = 2.5 cm, 4 cm 5mm = 4.5cm

The combined heights of the boxes are 3.3 + 2.5 + 4.5 = 10.3(cm)

-> There is 35 - 10.3 = 24.7(cm) above the boxes in the drawer left.
