then what observation do you found when analysing the

Answer 1

if we have two cubes that are joined end to end surface (vertically)..

we don't have the cubes value no length and breadth so, suppose the value is 1.

total surface area of cuboid is

2×(lb+bh+hl)

2(2×1+1×1+1×2)

5×2=10.

if you have any doubt than ask..
