Final answer:
Ashley can create metal cubes using metal casting or die-casting, which involves creating a model and then pouring molten metal into a mold to solidify into the cube shape.
Step-by-step explanation:
To form cubes from a metal sheet, Ashley can utilize a variety of manufacturing processes. A suitable method for creating detailed metal shapes like a cube is metal casting. Firstly, a model of the cube should be created, which can be done using a material such as clay or wax to precisely represent the cube's dimensions.
Following the model creation, a metal casting process can be initiated where a metal such as molten bronze or aluminum is poured into a mold that encases the model. Upon cooling, the metal takes the shape of the mold, resulting in metal cubes. Another useful process is die-casting, commonly used for metals and works well for creating uniform shapes in high volume.
