Find the volume of the prism

ok so it is for the triangle v = (base times height divided by two and then multiply by 12 so  

Step-by-step explanation:

15 times 12 is 180

it is 180cm cubed

i got 86 for this

hope this !

if you need an explanation just ask

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
