the way to find the volume of a prism is the following, get 3 measurements, the length, the width and the height (in this case you already have all 3) so simply multiply they together(2*5*8=80)
80 well tbh I really don’t know it I just multiplying the first 2 numbers then multiplied to the ten and I’m answering this question because I need this so I can wast h the add to keep using this app sorry
