Question

what is the lateral surface of an cube,rectangla,cuboide and square

Answer 1

Since cube and cuboid are 3 - d objects , so they have Lateral surface area.
Let l = length of cuboid, b = breadth , h = height
LSA = 2(l + b)h​

Let s = length of each edge of cube
LSA = 4s²

Now, square and rectangle are 2-d figures.
Area of square = side $\times$ side
area of rectangle = length $\times$ breadth
