    A rectangular sheet of metal, \[x\] cm by y cm ha square of side z cm cut from each corner The sheet is then bent to form a tray of depth z cm. The volume of the tray is

    A)  \[z(x-z)(y-z)c.c\].

    B)  \[xyz\,c.c.\]

    C)                  \[z(x-2z)(y-2z)c.c\]  

    D)                  \[(x+y)z\,c.c\]

    Correct Answer: C

    Solution :

     Length of the tray \[=(x-2z)\,cm\] Breadth of the tray \[=(y-2z)\,cm\] and height of the tray \[=z\,cm\] \[\therefore \] Volume of the tray \[=(x-2z)\,(y-2z)\,z.c.c.\]
