A pentagonal prism would fit the given description
A pentagonal prism would seem to fit the given description.
A triangular prism and a pentagonal based pyramid would fit the given description.
The answer obviously depends on the size of the prism!
A quadrilateral with diagonals of different lengths can be a rectangle or a kite. In a rectangle, the diagonals are equal in length, while in a kite, the diagonals are not equal and intersect at right angles. Other quadrilaterals, like trapezoids and irregular quadrilaterals, can also have diagonals of different lengths. Therefore, many quadrilaterals can fit this description, depending on their specific properties.

A rhombus would fit the given description.
112 inch cubes.
You cannot since the triangular prism has faces meeting at 60 degrees - all the faces of a cube meet at right angles. You can have small cubes sitting within a triangular prism but they cannot "fit" into it.
