Question

prove that total surface area of cubiod​

Answer 1

Answer:

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.

Answer 2

Answer:

Hence, the total surface area of six faces = (l × b) + (l × b) + (l × h) + (l × h) + (b × h) + (b × h).
