${\underline{\mathfrak{All \: formulas \: used \: in \: cuboid:-}}}$

✿Total surface area of a cuboid = Sum of the areas of all its 6 rectangular faces

✿Total Surface Area of Cuboid= 2(lb + bh +lh)=2(b × h) + 2(l × h)=2h(l + b)

✿LSA of Cuboid = 2h(l +b)

Surface Area of a Cube:

✿For cube, length = breadth = height

✿Suppose the length of an edge = l

✿Hence, surface area of the cube = 2(l × l +l × l + l × l) = 

✿Total Surface Area of Cube= 6l

✿Formula to find Lateral surface area of the cube is:

2(l × l + l × l)
