The campsite shop sells boxes of funshine cereal. the base of each box is a 180 mm x 60 mm rectangle. the shelf where the boxes are displayed is a 65 cm x 35 cm rectangle. work out the maximum number of boxes that will fit on the shelf.

There are 10 mm in 1 cm, so 180 mm is really just 18cm and 60 mm is just 6cm.

so how much area each box's base takes up?   18x6 centimeters, or 108cm.

the shelf is a 65x35 so is 2275 centimeters in available area.

how many times does 108 go into 2275?  well, 2275/108, that many would fit in the shelf

The volume is 2212m cubed
