Answer 2

The volume is 160

Explanation:

Explanation: To find the volume of the rectangular prism you need to multiply 8x20. The reason is because there are 20 cubes in each row (i'm sorry if i'm not good at explaining math very well). The way I found the volume was to count the amount of cubes on the side and multiply it by how many rows there were on top. So that brings me to 160. The product of 8x20.
