a cuboid
* * * * *
A prism, of which, a cuboid is a special case.
hexagonal prism
It is NOT as case of 'Some'. It is ALL rectangles are parallelograms.
Not for every parallelogram. Only for a rhombus (diamond) or square will the diagonals bisect the opposite angles they connect, and diagonals are perpendicular. In rectangles, the diagonals do not bisect the angles and are notperpendicular, but they do bisect each other.
better way to explain the picture one rec is standing up ont he left the other two are on there side on top of each other agaist the standing one so they make a bigger rec with all the little rectangles inside......
A quadrilateral has four sides & no other special properties. Any given side has two adjacent sides and one opposite side. There are two pairs of opposite sides. A parallelogram is a quadrilateral where both pairs of opposite sides are parallel to each other. Rectangles (including squares) are parallelograms. Rhombi (including squares) are parallelograms.
A skewed prism or, if the other faces are rectangles rather than parallelograms, a right prism.
triangular prisom
This shape has 2 opposite identical faces and some other which are parallelograms is a prism. A cylinder shape has 2 circular faces and one curved face.
A prism.

A skew triangular prism.
Prism, which a polyhedron with two congruent and parallel faces (the bases) and whose lateral faces are parallelograms.
a rectangular prism
It is a three dimensional shape whose faces are rectangles. There are three pairs of congruent parallel rectangles opposite each other. A smooth brick or box are good examples.
