6 .
used to make the box is
(a) 22 m
(b) 44 m
(c) 66 m
(d) 88 m?​

Answer 1

Answer:

We have,

The dimensions of a rectangular sheet =6.5 m×3m.

So,

total area of sheet =3.6×3

=19.5 m

2

The dimensions of box =15×6×5

length =15 cm

breadth =6 cm

height =5 cm

Then,

total area of Boxes =2(lb+bh+hl)

=2(15×6+6×5+5×15)

=2(90+30+75)

=2(195)

=390 c.m.

2

then,

Boxes no. =

Total Area of boxes

Total Area of sheet

=

10×390

195×10000

no. of Box =500 Boxes

Hence, this is the answer.
