Answer:
To find the volume of this prism, we must first find the area of the triangle and then multiply the area of the triangle by the prism's width.
We must know the formula for the area of a triangle;
A = BH
Where b is the base, and h is the height.
In this case, 4 is the base and 7.5 is the height, so we plug this into our formula:-
A = BH
A = 4(7.5)
A = 30
Now we must multiply the area of the triangle with the prism's length which is 8.
30(area of triangle) x 8(width of prism)
= 240 cubic meters (240^3 meters) is your volume.
