$\Large\mathcal\red{\boxed{\orange{Answer}}}$

The surface area of a solid object is a measure of the total area that the surface of the object occupies. Their work led to the development of geometric measure theory, which studies various notions of surface area for irregular objects of any dimension.

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.
