$A$ cube of side $4 \, cm$ contains a sphere touching its sides. Find the volume of the gap in between. (in $, cm^3$)

The curved surface area of a cylinder is $8800 \, cm^2$. If the radius of the cylinder is $28 \, cm$,find its volume in $cm^3$.

The length,breadth,and height of a cuboidal box are $25 \, cm$,$20 \, cm$,and $10 \, cm$ respectively. Find its total surface area in $cm^2$.

Curved surface area of a cone is $308 \, cm^2$ and its slant height is $14 \, cm$. Find $(i)$ radius of the base and $(ii)$ total surface area of the cone.

The dimensions of a cuboidal box are in the ratio $6: 4: 3$. The difference between the cost of covering it with white paper at the rate of $₹ 2.00$ per $m^2$ and with coloured paper at the rate of $₹ 2.50$ per $m^2$ is $₹ 1350$. Find the dimensions of the box.
