What is the volume of a 6m deep tank having Reactangular shaped top 6m X 4m and bottom 4m X 2m (computed through the use of Prismoidal formula)?

A two-hour duration storm event with uniform excess rainfall of 3 cm occurred on a watershed. The ordinates of streamflow hydrograph resulting from this event are given in the table. \[ \begin{array}{|c|c|} \hline \text{Time (hours)} & 0 & 1 & 2 & 3 & 4 & 5 & 6 & 7 \\ \hline \text{Streamflow (m}^3/\text{s}) & 10 & 16 & 34 & 40 & 31 & 25 & 16 & 10 \\ \hline \end{array} \] Considering a constant baseflow of 10 m\(^3\)/s, the peak flow ordinate (in m\(^3\)/s) of the one-hour unit hydrograph for the watershed is \(\underline{\hspace{2cm}}\). (in integer)

A 12-hour unit hydrograph (of 1 cm excess rainfall) of a catchment is of a triangular shape with a base width of 144 hour and a peak discharge of 23 m\(^3\)/s. The area of the catchment (in km\(^2\), round off to the nearest integer) is \(\underline{\hspace{2cm}}\).
