Ashley needs to form cubes from the metal sheet. She can use . Jack needs to manufacture a plastic water tank. He can use .

1. Metal fabrication

2. Rotational molding

Explanation:

Metal fabrication is a manufacturing process which is used to creat metal structure through different processes such as cutting, bending and assembling.So, a cube can be formed by the process of metal fabrication.as it require bending and cutting processes.

Plastic water tank are manufactured by the process of rotational molding in which a hollow mold is introduced with powdered plastic and then rotated continuously into an oven until the powdered plastic coats the walls of the mold. The mold is then allowed to cool down and it takes a shape of plastic water tank.

Hence, the correct answers are metal fabrication and rotational molding.
