Not necessarily.
A rectangle (or square).
a Cuboid
square base pyramid
The base of a cuboid is a rectangle.
The ajective "even" is not usually applied to faces, so it is difficult to answer the question. Two faces of a square based cuboid are square. The remaining 4 are rectangles.
A square prism is always a cuboid.
A cuboid can have 2, 4 or 6 square faces.
A square is a 2-dimensional figure, a cuboid is 3-dimensional.
A rectangle.
Not necessarily. The solid could be a square based cuboid (hexahedron).
A cube is a 3D square while cuboid is a 3D rectangle
A cross-section of a cuboid is the two-dimensional shape that results from cutting the cuboid with a plane. It is formed by the intersection of the plane with the three-dimensional cuboid. The cross-section of a cuboid can be a rectangle, square, or even a triangle, depending on how the cuboid is cut. The shape and size of the cross-section will vary based on the orientation and angle of the cutting plane relative to the cuboid.
