Step-by-step explanation:
- volume of wood required =volume of external cuboid - volume of internal cuboid
- volume of wood required = (lbh) external -( lbh) internal
- for external cuboid
- length(l) = 10cm
- breadth (b)= 8cm
- height (h)= 7cm
- thickness (t)= 1cm
- for internal cuboid
- length = l-2t = 10 - 2= 8cm
- breadth = b -2t = 8- 2= 6cm
- height = h -2t = 7-2=5cm
- volume required = (10×8×7) - (8×6×5)
- volume required = 560 - 240=320 cubic centimeter
- cost = 320 ×2
- cost =rs. 640
