Question

Total surface area of an open box whose length, breadth,and height are l,b,and h respectively is​

Answer 1

Answer:

TOTAL SURFACE AREA OF AN OPEN BOX WHOSE LENGTH,

BREADTH, AND HEIGHT ARE L,B,AND H RESPECTIVELY IS

Step-by-step explanation:

We know that this box is in the shape of a cuboid. So, the total surface area of cuboid = 2 (lb + bh + hl) where l, b and h are the length, breadth and height of the cuboid.

Answer 2

we know the formula to find the four walls of the box ( lateral surface) = 2(l+b)h

Area of the base = l×b

So, Surface area = 2(l+b)h + lb
