Question

How do you find surface area? If you can explain it that would be great :) thank you!​

Answer 1

SA=2lw+2lh+2hw

Explanation:

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. 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.
