A student uses 42 sheets of card to make three equal-sized cubes. How many sheets do they use for each cube?
The student uses a total of 42 sheets. This enables them to make three equal-sized cubes. We need to calculate how many sheets are used for each cube. Three divided by three is equal to one. This means that we need to divide 42 by three to work out the number of sheets required for one cube.
We can divide 42 by three using the bus stop method. Four divided by three is one remainder one. 12 divided by three is equal to four. This means that 42 divided by three is equal to 14. 14 sheets of card are used for each cube.
We can check this by multiplying 14 by three. 10 multiplied by three is equal to 30. Four multiplied by three is equal to 12. This means that 14 multiplied by three is indeed 42. We can therefore conclude that each cube does indeed use 14 sheets of card.
