Working out area

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.

I converted the measurements all in the same units as centimetres as I divided 180mm divided by 10 = 18cm then I divided 60mm divided by 10 = 6cm.

18 cm x 6 cm = 108 cm.

Then I multiplied 35 cm by 65 cm = 2275 cm.

Then the final answer is 2275 cm divided by 108 cm = 21.06 cm.

So maximum number of boxes which would fit would be 21 boxes.

After you've placed 5 rows of 3 boxes, some space remains. However, it's in an L-shape that allows only one more box to fit in.

So 5 x 3 = 15 plus the L Shape = 16 boxes.

Yes (assuming you meant "plus one box in the L-shape").
