Answers:
  • 22. a. Dangers of bleach: corrosive, danger for the environment.
  •  b. The safety symbols for bleach:
  • 23. a. The dimensions of one shoebox equals: 20 x 30 x 15 cm = 9,000 cm3.
  • The dimensions of the large box is: 80 cm x 1.5m (150 cm) x 70 cm = 80 x 150 x 70 = 840,000 cm3.
  • You can stack the boxes…
  • The width of the big box is 80 cm; therefore you can have 80/20 = 4 boxes wide.
  • The length of the box is 1.5 m = 150 cm; therefore 150/30 = 5 boxes deep.
  • The height of the boxes is 70 cm; therefore you can have 70/15 = 4 boxes tall, with some space left over at the top.
  • So, overall you can fit 4 x 5 x 4 = 80 shoeboxes in the large box
  • b. There will be some space left. The total size of the large box - the size that is taken up by the 80 shoeboxes = 840,000 cm3 - (80 x 9,000 cm3) = 840,000 - 720,000 = 120,000 cm3.
