Question

external dimension of a closed wooden cuboidal Box length 30 cm breadth 25 cm height 20 CM if the thickness of the wood is 2cm all around find the volume of the wood contained cuboidal box formed

Answer 1

the external volume is =(30 *25*20)cc
= 15000cc.
the internal length =30-4=26 cm
the internal height=20-4 =16cm
the internal breadth= 25-4=21cm
the internal volume there =(21*26*16)cc= 8736cc
therefore the volume of the wood =(15000-8736)cc= 6264cc
