Answer:

Step-by-step explanation:
First we need to find area of the triangle with a base of 4 cm and a height of 5cm, and then multiply that by the length of the prism of 15cm.
The area of the triangle is given by the formula:

where b is the base:
and h is the height: 
thus, in this case we have:

And now, the volume will be the area of the triangle multiplied by the length
of the prism:

Substituting the known values:

The volume in cubic centimeters is 150.
