a trigonometric function that is a relation between the angle of elevation and the 2 sides of the rectangles is the tan

$\tan \theta=\frac{opp}{adj}$ $\tan \theta=\frac{20}{30}=\frac{2}{3}$

find the inverse

$\begin{gathered} \tan ^{-1}(\frac{2}{3})=\theta \\ \theta=33.69º \end{gathered}$

The formula for the volume of a pyramid is (1/3)area of the base x height.
And the questions gives us all the information we need! All we need to do is plug in the values.

V = 1/3 b x h
V = 1/3 x 625 x 30
V = 10 x 625
V = 6250 cubic meters

Hope this helps!
