Irregular 3-dimensional shapes.
Adding depth makes a 3D object from a 2D shape.
They have length, width and depth
2d shapes only have length and width, while 3d shapes have length, width and depth.
Placing irregular shapes of an object on the frontal plane during an oblique drawing simplifies the representation by providing a clear reference point for the viewer. It helps maintain proportionality and perspective, ensuring that the dimensions and angles of the object are more easily understood. Additionally, this positioning allows for better visualization of the object's depth and three-dimensionality, enhancing the overall clarity of the drawing.
A cube is, by definition, regular. Do you mean a cuboid? The volume of a cuboid is length × width × height or length × width × depth (where depth and height are the length in the third dimension). For irregular three dimensional shapes, divide them up into smaller shapes for which the volume can be calculated and add them together. ----------------------------------------------------------------------------------------- For real world irregular three dimensional object it is impractical to try to split the object up into smaller shapes. In this case get a cuboid of water (or other liquid) in a tank, measure its volume (as above), submerge the object completely in the liquid and re-measure the volume of the liquid (the tank should have excess capacity greater than the volume of the object so that no liquid spills): the volume of the object is the difference between the two measurements of the volume of liquid.

Shapes that have length, width and depth are considered to be 3 dimensional
They have length, width and depth
Height, width, and depth.
2d shapes are circles, ellipses, polygons (triangles, quadrilaterals, pentagons, etc.), angles, other non polygon shapes (like when you draw a star and the lines cross over each other. 3d shapes are shapes with added depth, such as tetrahedron, pyramid, prism (such as a cube), sphere (a ball), cone, etc.
They have one fewer dimension; they lack depth.
2d shapes only have length and width, while 3d shapes have length, width and depth.
Three dimensional shapes are shapes with height, width, and depth. In contrast, two dimensional shapes only have height and width, or length and width.
