Someone help me this is my last page and i dont know what to do, i will award a lot of points to whoever answers them all. would a 100 be enough?

i pretty sure it is

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

pls refer ro the top for answer

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
