Ren says the front and right-side views on the card fix a 3 by 3 building exactly. Which reply is justified?
3 by 3 base of stacked cubes. Front view, tallest stack in each column from the left: 2, 1, 1. Right-side view, tallest stack in each row (row 1 on the left): 1, 2, 1. 3 by 3 base of stacked cubes. Front view, tallest stack in each column from the left: 2, 1, 1. Right-side view, tallest stack in each row (row 1 on the left): 1, 2, 1. 3 by 3 base of stacked cubes Front view Right-side view - Yes: exactly 8 cubes, because the front view and the side view are added together
- No: between 4 and 10 cubes match both views, so the views do not fix the building
- Yes: exactly 4 cubes, because each unit of the front view is one cube in a fixed place
- Yes: as many as 12 cubes could be hidden behind the taller stacks
