Problem Analysis

To solve this problem, we need to find the amount of wood used by each workshop. We know that the first workshop produced 8 sets of school furniture and the second workshop produced 12 sets of the same furniture. Additionally, the first workshop used 480 cm less wood than the second workshop.

Solution

Let's assume that the second workshop used x centimeters of wood. Since the first workshop used 480 cm less wood, it used (x - 480) centimeters of wood.

To find the value of x, we can set up an equation based on the given information:

8(x - 480) = 12x

Now, let's solve this equation to find the value of x:

8x - 3840 = 12x -4x = 3840 x = -3840 / -4 x = 960

Therefore, the second workshop used 960 centimeters of wood, and the first workshop used (960 - 480) = 480 centimeters of wood.

Answer

The first workshop used 480 centimeters of wood, and the second workshop used 960 centimeters of wood.
