Oh, dude, a triangle has three sides, right? So, it must have three flat surfaces too, like the three amigos hanging out together. I mean, unless one of them is feeling rebellious and decides to go all 3D on us, but that would be a whole different shape drama.
a rectangle
A cuboid has 6 sides/faces/flat surfaces.
A cube has 6 faces, so it would have 6 flat surfaces
cube There are a great many solid shapes that have only flat surfaces.
2 flat surfaces unless it is rolled up in which case it has 2 curved surfaces.
There are 5 flat surfaces.
5 Flat surfaces 4 flat surfaces (3 for the sides and 1 for the base).
a rectangle
Triangle None of them.
5 flat surfaces.
Flat surfaces: 6Curved surfaces: 0.
There are 2 flat surfaces, both are circles.
It has 6 faces which are its flat surfaces.
2 flat and 1 curved
A cuboid has 6 sides/faces/flat surfaces.
A square has 4 flat surfaces.
A cuboid has got six flat surfaces.
