In order to answers these types of calculation, we will have to practise two key skills.
Key skill 1: to estimate the volume of an object using cubes Key skill 2 - to estimate the volume of an object, using given information
SLIDE 4
Watch Me
Key skill 1: to estimate the volume of an object using cubes Shape A has a volume of 12cm. Estimate the volume of the other
- shapes. Which shape has the greatest volume?
3
You may use cubes to make these cuboids. if you have some at home.
SLIDE 5
Key skill 1: to estimate the volume of an object using cubes Shape A has a volume of 6cm. Estimate the volume of the other
- shapes. Which shape has the greatest volume?
