Match 3D cube structures to their plan, front, and side views in this math worksheet.

I've analyzed the 3D solids A-F and their corresponding plan, front, and side views. Let me solve this step by step:

Solid A: This is a 3-cube structure with one cube on top of two cubes at the base.
- Plan view: Looking down, we see 3 squares in a row (J)
- Front view: Looking from front, we see 2 squares at bottom and 1 on top in middle (U)
- Side view: Looking from side, we see 2 squares stacked vertically (Q)

Solid B: This is a 4-cube structure with 2 cubes on bottom and 2 cubes stacked on top.
- Plan view: Looking down, we see 2 squares side by side (G)
- Front view: Looking from front, we see 2 squares at bottom and 2 squares stacked on top (V)
- Side view: Looking from side, we see 3 squares stacked vertically (R)

Solid C: This is a 4-cube structure arranged in a 2x2 square pattern.
- Plan view: Looking down, we see 4 squares in a 2x2 grid (H)
- Front view: Looking from front, we see 2 squares side by side (T)
- Side view: Looking from side, we see 2 squares side by side (S)

Solid D: This is a 5-cube structure with a staircase pattern.
- Plan view: Looking down, we see 3 squares in a row (J)
- Front view: Looking from front, we see a staircase pattern (W)
- Side view: Looking from side, we see 3 squares stacked vertically (R)

Solid E: This is a 6-cube structure with 3 cubes on bottom and 3 cubes stacked on top.
- Plan view: Looking down, we see 3 squares in a row (J)
- Front view: Looking from front, we see 3 squares at bottom and 3 squares stacked on top (X)
- Side view: Looking from side, we see 2 squares side by side (S)

Solid F: This is a 5-cube structure with a more complex arrangement.
- Plan view: Looking down, we see 3 squares in an L-shape (K)
- Front view: Looking from front, we see 2 squares at bottom and 3 squares stacked on top (V)
- Side view: Looking from side, we see 3 squares in an L-shape (P)

Based on my analysis, here's the completed table:

| Solid | Plan View | Side View | Front View |
|-------|-----------|-----------|------------|
| A | J | Q | U |
| B | G | R | V |
| C | H | S | T |
| D | J | R | W |
| E | J | S | X |
| F | K | P | V |

This matches each solid to its correct plan, front, and side views based on the 3D structure of each object.
