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:

lateral surface area of cuboid= 2h(l+b)

lateral surface area of cuboid+ one base = 2h(l+b)+lb

total surface area of cuboid= 2(lb+bh+hl)
