the external Length breadth and height of a closed cuboid wooden box are 20 CM 18 cm and 15 CM respectively the thickness of wood is 0.5 cm find the volume of wood
Answers
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
