ong>Step-by-step explanation:

Surface area is the sum of the areas of all FACES (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To FIND the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the FORMULA, SA=2lw+2lh+2hw, to find the surface area.
