length of rectangular sheet =13m
breadth of rectangular sheet =3m
area of rectangular sheet =
$39m ^{2}$
length of cuboid =15cm
breadth of cuboid =6 cm
height of cuboid =5 cm
TSA OF CUBOID =2(lb+bh+hl)
=2(15*6+6*5+5*15)
$m {}^{2}$
$390m {}^{2}$
no of boxes : area of sheet /area of cuboid
=390/39
= 10 boxes..
