Answer 1

Answer:

The Cost of the cardboard For the Box Rs.583.20

Step-by-step explanation:

For a Cuboid

Length = 45cm

Breadth = 36cm

Height = 16

Surface Area = 2(lb + bh + lh)

    = 2( 45x36 + 36x16 + 45x16 )

    = 2( 1620 + 576 + 720 )

    = 2 x 2916

    = 5832 sq.cm.

Rate of cardboard = Rs. 10 paise per sq.cm.

Cost of Card Board = 5832 x 10

                                = 58320 paise

                                = Rs. 583.20
