In art class, Wei Lin builds a solid using identical unit cubes. The bottom layer has 3 cubes placed side-by-side in a straight row. On top of the leftmost cube of the bottom row, he stacks 2 more cubes (one directly above the other). When Wei Lin looks at his solid from directly in front, how many unit squares does he see in the front view?

Worked Solution
Step 1: Identify what the front view shows. The front view is the 2-D shape you see when looking straight at the solid from the front — each visible cube face counts as one unit square.
Step 2: Count the squares in the bottom row of the front view. The bottom layer has 3 cubes in a row, so the bottom row of the front view shows 3 unit squares.
Step 3: Count the squares in the stacked column. 2 cubes are stacked on top of the leftmost bottom cube, adding 2 more unit squares above the leftmost square.
Step 4: Add up all visible squares: 3 (bottom row) + 2 (stacked above leftmost) = 5 unit squares.
Final answer: 5.
Answer: 5
Correct answer: 5
