Question

Which shape isn't for a cross section of a cube to take

Answer 1

I mean which shape is notnpossible

Answer 2

Like I know I can make a rectangle and a square

Answer 3

are you provided a list of possible shapes, or are you just listing impossible ones ?

Answer 4

No I have equilateral triangle
Rectangle
Square
Octagon
Rhombus
Isosceles triangle

Answer 5

ah. which one can you rule out already?

Answer 6

I know that a square is possible and a rectangle is also possible

Answer 7

an octagon requires 8 sides, so that one is not possible. what about a triangle? can you think of how you might generate one through a cross section ?

Answer 8

Yes because two triangles make a square we did a slanted cross section we would get that

Answer 9

you could get an equilateral triangle by cutting at the corner tip. if you slant the cut a little, you could also get a non-equilateral triangle, even an isosceles

Answer 10

And we could also get a rhombus because it has 4 sides

Answer 11

And the only thing we can't get is a octagon

Answer 12

yes but the cut would have to be at two opposite vertices and at two opposite midpoints

Answer 13

hm..

Answer 14

looks like that is all. all of the above except octagon
