ACTIVITY 3 WEIRD AND WONDERFUL
New Zealand is just one of many countries that has amazing plants and trees. In fact, the African desert is home to some pretty incredible plants, like the cactus. Some cacti are able to survive on as little as 3 millilitres (ml) of water a day. Wow!
Let’s imagine that you are given a cactus for your birthday. To keep it alive, you must give it 3 ml of water every day.
Over one full year, how much water will you need to give your cactus plant?
On your blog, tell us how to solve this maths problem. You can write your answer in words, use a Sketchpad image, or post a video explaining how you would figure it out. Be sure to give us your final answer in millilitres (ml).
1095 mls

If I was given a cactus for my birthday my answer would be to give it 1095 mls for a full year. The way I got this answer is I multiplied 3 mls by the days of the year. There are 365 days in 1 year and my total was 1095. I got my answer by getting help from the google calculator on my chromebookš I put in 3 x 365 and it came up with 1095.
