Answer 2

$\huge \pink{Solution Chimkandi}$

Since, the area of a cuboid (6 faces) = 2(lb+bh+hl)

where,

l : length,

b : breadth,

h : height of cuboid.

But here talking about the area of 4 walls of a cuboid.

Assume, area of 4 walls = 2(bh+hl)

Note : Area (=2lb) are neglected because they are base and the top.
