_____________________________________________________________
External Dimensions = 25 X 18 X 15
Internal Dimensions = 23 X 16 X 13
_____________________________________________________________
Rice holding capacity = 23 X 16 + 2 X 13 (23+16)
= 368 + 26 (39)
= 368 + 1014
= 1382 cm^3
____________________________________________________________
Volume of wood = LBH-lbh
= 25 x 18 x 15 - 23 x 16 x 13
= 6750- 4784
= 1966 cm ^3
