Answer:

878 cm cube

Step-by-step explanation:

External length, breadth, height= 20 cm, 18cm, 15cm respectively

Thickness of the wood=0.5

Internal length=20-1=19cm, breadth=18-1=17cm, height=15-1=14cm

Volume of the cubiodal wooden box= l×b×h

= (20×18×15) - (19×17×14)

= 5400-4522

= 878 cm cube

volume of wood  = 878 cm³

Step-by-step explanation:

the external Length breadth and height of a closed cuboid wooden box are 20 CM 18 cm and 15 CM

Thickness of wood  = 0.5 cm

Internal Dimension of Wooden box = (20 - 2 *0.5) = 19 cm

18 - 2*0.5 = 17 cm

15 - 2*0.5 = 14 cm

Volume of wood =  20 * 18 * 15 - 19 * 17 * 14

= 5400 - 4522

= 878 cm³

volume of wood  = 878 cm³
