■HEY DEAR HERE IS YOUR ANSWR. .
●VOLUME of the box = 10cm×8cm×7 cm =560cm^3
● THICKNESS of wooden box = 1 cm
=>inner length = l - 2w = 10-2 =8 cm
=>inner breadth = b-2w= 8-2=6cm
=>inner height= h - 2w= 7-2 = 5cm
=> Inner volume => 8 ×6×5 cm^3 =240cm^3..
●Required volume => 560-240 cm^3= 320cm^3
●THE COST of 1cm^3 =2 rs
then the cost of 320 cm^3 = 320cm^3×2 rs= 640..
