The campsite shop also sells boxes of Pick-Me-Up teabags. The base of each box is a 120 mm square. 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. |

So to work this out I have converted 120 mm divided by 10 = 12 cm then i have divided 2275 cm by 12 cm squared = 189 cm squared. The final answer I got was 189.58 so the maximum number of boxes would be 189. |

You should have divided by 144. However, after placing two rows of five boxes, the remaining space is in an L-shape (at best) that doesn't allow any more boxes to fit in.

Mr. Willow, a similar problem: You have a rectangle with dimensions 240 by 720. How many 120 by 120 squares can you draw inside that rectangle? |

So do you divide 2275 cm by 144 to get the final answer?

240 by 700 is SMALLER than 240 by 720. So HOW did you get 14? Can't you see that's impossible? |
