Answer:

Cut the prism into 2 parts like the picture below

Name the upper part A, and the lower part B

Calculate the volume of part A:

12 - 8 = 4 cm

4 * 5 * 6 = 120
cm^(3)

Calculate the volume of part B:

15 * 8 * 6 = 720
cm^(3)

Volume of the whole prism:

Volume of part A + volume of part B

120 + 720 = 840
cm^(3)
