A) \[828\text{ }c{{m}^{3}}\]
B) \[672\text{ }c{{m}^{3}}\]
C) \[500\text{ }c{{m}^{3}}\]
D) \[1000\,c{{m}^{3}}\]
Correct Answer: B
Solution :
[b] Square of side 2 cm is cut from rectangular sheet as shown in the figure. Then, length of the box \[=25-2\times =25-4=21\] and breadth of the box\[=20-2\times 2=20-4=16\] and height of the box will be 2 cm. \[\therefore \]Volume of the box = Length \[\times \]Breadth \[\times \]Height \[=21\times 16\times 2=672\,c{{m}^{3}}\] |
