To determine the depth of a 3D shape, you typically measure the distance from the front face to the back face along a perpendicular line. This measurement can be taken using a ruler or caliper if the object is physical, or by analyzing the dimensions in a 3D modeling software if it's a digital shape. If the shape has a complex form, you may need to break it down into simpler components to accurately assess the depth.
a 3D shape has 3 dimensions; length, with and depth
A 3D shape must have length x width x depth.
To calculate the depth of a 3D shape, you typically measure the distance from the front to the back of the shape, often referred to as the "thickness" or "depth." For regular shapes, such as cubes or rectangular prisms, this can be obtained directly from their dimensions. For more complex shapes, depth can be determined using geometric formulas or by analyzing cross-sectional areas. In some cases, depth can also be inferred from spatial coordinates in a 3D modeling context.
Adding depth makes a 3D object from a 2D shape.
A cut diamond is a 3D object as it has length, width and depth (even if it is roundish like a pebble)

2d is a flat shape with only 2 dimentions (width & length) 3d is a shape with 3 dimensions (width, length and depth)

A rhombus is a four sided polygon, a quadrilateral. It is a 2d shape. 2d shapes have 2 dimensions, like length and width. 3d shapes have 3 dimensions, like length, width and depth.
The difference between 2d and 3d shapes is that, a 2d shape is flat, has no volume and depth and cannot be handled while a 3d shape can be held, has depth, volume and can hold things inside it. These are the dimensional shapes which are mostly used in geometry.
A sheet of A4 paper could be classed as a plane 2D shape, as it has length x width. A shoebox is an example of a 3D shape, as it has length x width x depth.
An OVAL is a 2-dimensional shape. (A squashed circle of you like). It only has width , and length, but no depth.
3D stands for three dimensional. If a shape has length, width, and depth, then it has three dimensions, thus it is 3D.
It depends on the 3d shape.
