Wooden blocks are stacked to form a cube 3 block wide, 3 block long, and 3 block high. How many blocks are used?

27 blocks are used

Right.

To find the number of blocks used to form a cube, you need to find the volume of the cube. The volume of a cube is given by the formula:

Volume = side length ^ 3

In this case, the side length is 3 blocks.

So, plugging in the values into the formula:

Volume = 3^3 = 27

Therefore, 27 blocks are used to form the cube.
