Question $2$ please help $me$ with this one! $I\text{'}m$ pretty sure the answer $is$ NOT $50\mathrm{.}67.$ thank you

A volume $is$ described $as$ follows:

the base $is$ the region bounded $byy=5-\frac{5}{4}{x}^2$ and $y=0$

every cross section parallel $to$ the $x-$axis $is$ a triangle whose height and base are equal.

Find the volume $of$ this object.
