Volume of a Prism = Area of cross section * Height
Volume of Pyramid = (1/3) * Area of base * Height
Let the area of the triangle be x.
Volume of Prism = x * 2
Volume of Pyramid = (1/3) * x * 5
Volume of Prism$\displaystyle = 2x
$
Volume of Pyramid$\displaystyle = \frac{5x}{3}
$
Ratio of volumes:
$\displaystyle
2x : \frac{5x}{3}
$
Can you simply that?
