Answer 1

Answer:

Step-by-step explanation:

2620 Rs

Step-by-step explanation:

The givens are:

Outer length = 20 cm

Outer width = 16 cm

Outer height = 8 cm

Therefore, outer volume = Length*Width*Height = 20*16*8 = 2560

Since the thickness of the wooden box is 1 cm,

Inner length = 20-2(1) = 18 cm

Inner width = 16-2(1) = 14 cm

Inner height = 8-2(1) = 6 cm

Therefore, the inner volume = 18*14*6 = 1512

Therefore, the volume of the wood used = Outer volume - Inner Volume = 2560-1512 = 1048

Since the cost of 1  = 2.5 Rs, therefore, the total cost = 2.5*1048 = 2620 Rs
