If each side of a cube is increased by $10 \%$,the volume of the cube will increase by (in $\%$).

$A$ cylindrical bucket is $72\, cm$ high and $28\, cm$ in diameter and is full of water. This water is emptied into a rectangular tank whose length and breadth are $66\, cm$ and $28\, cm$,respectively. What will be the height of the water level in the tank? (in $cm$)

The number of bricks,each measuring $25\,cm \times 12.5\,cm \times 7.5\,cm$,required to construct a wall $6\,m$ long,$5\,m$ high,and $0.5\,m$ thick,if the mortar occupies $5\%$ of the volume of the wall,is:

If the surface areas of two spheres are in the ratio $4:9,$ then the ratio of their volumes will be

$2$ cubes have volumes in the ratio $1:27$. The ratio of the area of the face of one to that of the other is

If each edge of a cube is increased by $50 \%$,the percentage increase in surface area is (in $\%$)
