Answer 1

Answer:

Hey mate here's your answer.

Step-by-step explanation:

Outer dimensions of box are 20cm*16cm*8cm

Thickness is 1 cm.

Therefore the internal dimensions of box will be

18cm*14cm*6cm (subtracting 2 from all three dimensions as the length of all dimensions will decrease by 1 cm from both ends).

Outer volume of box=20*16*8

=2560 cm³

Inner volume of box=18*14*6

=1512 cm³

Therefore, volume of book required to make box =outer volume of box-inner volume of box =2560-1512

=1048 cm³

Now, cost of wood=₹ 2.5 per m³

Therefore cost of making box of volume 1048 cm³ = 1048*2.5

=₹2620
