Idea 7of 22Builds onThe front view: the tallest in each column
A view cannot show how deep
Can a front view tell you how far back a building goes?
Today you'll discover
- why rows behind disappear from the front
- which view shows how far back
- the fewest cubes a view needs
Think firstA is one row. B is three rows the same.
Will A and B have the same front view?
Decide first, then press Next. Compare the two drawings under the buildings square by square.
Two buildings side by side: A is one row of stacks 2, 1, 1; B is three such rows, one behind another. Under each, its front view: the same columns 2, 1, 1. Then the cube counts, 4 and 12, and then the side views, 1 column for A and 3 for B.

The big idea
A front view hides depth: it cannot show how many rows go back.
Why it happensThe rows behind sit straight behind the front row, so from the front they are hidden, however many there are.
Where it goes nextThat is why builders never work from one view. The side or top view says how far back a building goes.
Key word
- depth
- how far an object goes back, from its front to its back
Ready to use it?
- Find two buildings with the same front view.
- Say which view shows how deep a building is.
