1. Kate made a rectangular prism by putting two cubes together, as
shown below. Then she glued pieces of paper on each face of the
rectangular prism that has the same size as the face of the cube.

I prepared 12 pieces of
colored paper because
each cube has 6 faces.
But I needed only 10
pieces of colored paper.

How many pieces of colored paper are needed to completely
cover a rectangular prism made with six cubes as shown below?
