Maths task

We did some cool math tasks where we had to work out a dimensions for a swimming pool and three more tasks. Here is my work sheet and how I worked it out...first I will be showing you my swimming pool sheet and then I will be showing you my other sheets...enjoy!

                                                                                                                                                             


Parkvale school

The Parkvale pool needs to be drained and refilled because it has become too dirty.

These are the dimensions of the pool:
     12x25=300
                                                               10x25=250
                                                                                                        2x25=50            
                                                                                                       300x2=600
  •  How much water in m3 is needed? 12x25x2=600,00
  • How many litres of water is needed?


Extra for Experts:
  • The tap to fill the pool pumps 50,000 litres per hour. How many hours would it take to fill the pool?
  • For each 1000 litres of water, 1 gram of chlorine is needed. How much chlorine needs to go into the pool?
  • Design a different pool in 3D (like above) and work out its volume in m3 and litres. Tip: start with a cube or rectangle




Stage 5&6 Volume

Do your working out in your maths book - show all of your working out.


  • A container has a volume of 96m3. What are all the possible dimensions of this container?

  • A pool has a volume of 180m3. What are all the possible dimensions of this container?

  • A lunchbox has the volume of 280cm3 What are all the possible dimensions of the lunch box?






1x28x10=280cm3
28x10x1=280cm3
10x1x28=280cm3
10x28x1=280cm3
1x10x28=280cm3
28x1x10=280cm3
