Question 12

Kiesha has a fish tank which is the right size for 3 fish. A friend gave her 3 more fish and she needs to get a tank with double the volume. She could do this by buying a new tank which is:
  1. double the width and the length of the old tank
  2. double the width, length and depth of the old tank
  3. half the length and double the width and depth of the old tank
  4. half the length and double the depth of the old tank
  5. half the length and double the width of the old tank
