Answer 1

${❥}\fbox\red{A}\fbox\orange{N}\fbox\purple{S}\fbox\green{W}\fbox\blue{E}\fbox\pink{R}$

Required answer-:

Given that,

Length=5m

Breath =3m

Height =4m

We know that,

Total surface area of sheet=2(lb+bh+hl)

=2(5×3+3×4+4×5)

=2(15+12+20)

=2×47

=94

But by condition without line.

Total surface area-lb

94−15=79m²
