Problem # $02$: Using differential method, determine the i$)$ volume and the ii$)$ surface area oriented along $a_z$ and $a_{-}$ of the $3$D shape shown in the Fig. $1.$ The range of variables are;

$01,0\frac{7}{4},0z2$

Hint: For the surface area part, out of the total six faces; you are required to find only $2$ of them.
