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.
Step-by-step explanation:
example
- 3 inches by 4 inches ,and it stand 5 inches tall
- 1
- l=length,w=width,h= height
- l=4
- w=3
- h=5
