Question

Here's an analogy that is actually for my son'english homework, but it's got me stumped. Square is to plane as cube is to __________. Any ideas?

Answer 1

Not sure about this but as far as my knowledge about geometry its 3-D Plane.

Answer 2

My thought is that it my be an error and they meant.. Cube is to plane as Square is to line. Do you think that would make sense?

Answer 3

No because a cube has six sides or planes and a square only has four lines and a plane is a flat geometric shape and a 3-D plane is a solid while a line is 1-D plane.

Answer 4

Now for your way of changing it it wouldnt be: Cube is to plane as Square is to line. It would actually be: Line is to Square as Square is to cude

Answer 5

It is 5th grade so I'm thinking the logical reasoning would go a plane is the side of a cube and a line is the side of a square.

Answer 6

But the analogy does go like that and it is 3-D plane.

Answer 7

Doesn't work out quite right with upper level mathematical definitions of planes and lines, but might be in sync with 5th grade

Answer 8

And no that wouldnt work because a square is on a Plane while a cube is on a 3-D plane. Think about it it makes sense. And planes dont techinically make a cube squares do and squares arent a plane they are on a plane and a cube is on a 3-D plane.

Answer 9

The goofy thing is, it's not even a math problem.

Answer 10

Well i have explained why it is correct for the missing word to be 3-D plane

Answer 11

I get what your saying, but 3D planes are a few years ahead of his grade level.

Answer 12

You said its not his math homework and knowing hes in 5th grade its not geometry so which subject is it?

Answer 13

And while the side of a cube is not technically a plane but rather a part of a plane, the same is true, the side of a square is not technically a line but rather a part of a line

Answer 14

English, the idea is to test that he understands what an analogy is

Answer 15

Have you asked if he has be learning what 3-D planes or shapes are?

Answer 16

Yeah, he knew a cube is a 3 demensional shape, but had never heard of a 3 D plane

Answer 17

I think I'll close this and rephrase the question, not that important, just an interesting debate I'd like to get some imput in. My son has already answered the question by explaining what an analogy is and why he doesn't have the back knowledge to answer this one

Answer 18

Thats good : )
