Answer:
12x5=60
12x5=60
16.5x2=33
13x16.5=214.5
12x16.5=198
60+60+33+214.5+198=565.5ft³
Step-by-step explanation:
you will need to find the surface area of the triangular prism. for this you will need to get the area of every side and then add them all together. You will use "ft³" at the end because this is a 3D shape and i assume that not putting the unit of measurement at the end will give you half credit.
hope it helps
