Answer #1

Internal edge =1m

Thickness of wood=5cm

External length=1m+10cm=1.1

       Breadth =1m+10cm=1.1

Height =1m+5cm=1.05

Volume of the wood =outer-inner volume

                  =1.1*1.1*1.05-1*1*1

                 =1.2705-1.0000

                  =0.2705m3

Cost of wood 1m3=Rs9600

So,cost of 0.2705m3=9600*0.2705                                                    =Rs2596.80
