1.	12. In the given figure, shows the shape of asolid copper piece (made of two pieces)with dimensions as shown. The faceABCDEF is the uniforrm cross-section.Assume that, the angles at A, B, C, D, E andF are right angles. Calculate the volume ofthe piece.5 cm8 cm03 orn
Answer» Volume of first piece.V1 = 2252 = 220 cm^3 Volume of second pieceV2 = 2283 = 528 cm^3 Total Volume of given piece= V1 + V2= 220 + 528= 748 cm^3

Answer»

Volume of first piece.V1 = 22*5*2 = 220 cm^3

Volume of second pieceV2 = 22*8*3 = 528 cm^3

Total Volume of given piece= V1 + V2= 220 + 528= 748 cm^3
