Geometry

In an isometric drawing, the three principal axes (length, width, and height) of a 3D object are equally foreshortened. This means that the relative proportions of the object along these axes are maintained in the 2D isometric drawing.

To determine the ratio of the actual dimensions of the rectangular prism, we use the given dimensions:

Length = 7.5 units

Width = 5 units

Height = 1.5 units

The ratio of the dimensions is: 7.5:5:1.5

To simplify this ratio, divide all terms by the greatest common divisor (GCD) of the numbers. The GCD of 7.5, 5, and 1.5 is 0.5:
