Hi Kiara, by definition a prism is three-dimensional. A prism is a type of 3D shape with flat sides. It has at least two ends that are the same shape and size. Cubes and cuboids are good examples. The general technique to find the area, is to calculate the area of all of the faces of the prism seperately and then add them up. So for a cuboid (a shape with 6 sides), we would add the areas for the 2 square faces to the areas of the other 4 rectangular faces.
