Answer:[tex]\left ( 11-2x\right )\times \left ( 9-2x\right )\times \left ( x\right )[/tex]
Step-by-step explanation:
Given data
breadth=9 in
Length=11 in
Now a square of side x is cutted for each corner such that the cardboard is made into a open-top box with
length=11-2x
breadth=9-2x
height=x
Here substract 2x because from both sides of length and breadth x units are reduced.
therefore volume of new open-top box is
Volume(v)=[tex]\left ( 11-2x\right )\times \left ( 9-2x\right )\times \left ( x\right )[/tex]
