Particles that form a sedimentary rock by accumulating are called sediment. Before being deposited, sediment was formed by weathering and erosion in a source area, and then transported to the place of deposition by water, wind, ice, mass movement or glaciers which are called agents of denudation.
A cuboid is a box-shaped solid object. It has six flat sides and all angles are right angles. And all of its faces are rectangles.
A Parallelogram is a four-sided shape with opposite sides that are both parallel and equal in length. The area of a parallelogram is the base times the height. A Trapezoid is a four-sided shape with at least one set of parallel sides. The area of a trapezoid is the average of the bases times the height.
