Volume: Intuitive introduction volume of a cuboid

STUDENTS:

A cube is a 3D square. A cuboid is a 3D rectangle. We can make a cuboid out of cubes. Interact with the applet below for a few minutes. Then answer the questions that follow.

In the applet above, create a cuboid that has 1 layer measuring 3 units long by 4 units wide. How many cubes make up the cuboid? Once you have submitted your answer, draw a picture of the cuboid in your book.

Now make this cuboid 2 layers high? Now how many cubes make up the cuboid? Once you have submitted your answer, draw a picture of the cuboid in your book.

Create a cuboid that has one layer measuring 5 units long by 3 units wide. How many cubes make up this cuboid? Once you have submitted your answer, draw a picture of the cuboid in your book.

Now make this cuboid 2 layers high. How many cubes make up the cuboid? Once you have submitted your answer, draw a picture of the cuboid in your book.

Now make the cuboid 3 layers high. How many cubes make up the cuboid?

What if the cuboid were 10 layers high. (you won't be able to make this on the activity). How many cubes do you think you would need?

How can we EASILY determine the number of cubes that fit inside ANY cuboid? Describe.
