What do you understand by Surface area? How to determine Surface area |
|
Answer» 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. |
