Answer:  y = 6

The triangle has a base of y and a height of 5. The area of the triangle is

area = (1/2)*base*height = 0.5*y*5 = 2.5y

which multiplies with the prism's depth 8 to get 2.5y*8 = 20y

The expression 20y represents the volume of the prism, which we are told is 120 cubic meters, so 20y = 120 solves to y = 6 after dividing both sides by 20.
