What is the formula of calculating the surface are of cuboid ?​ - Mathematics

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.

Explanation:

i-dk if this will help srry if it doesn't

Explanation:

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

curved surface area of cuboid is 2 x ( l + b + b )

l is length

b is breadth

h is height

i think it's a but not entirely sure
