How do I find the volume of a triangular prism using the area

Volume of triangular prism is

V = base area x height

a, V = 40 x 16 = 540

b, V = 64 x 12 = 768

c, V = 80 x h

d, V = (5 x 12 x 1/2) x 30 = 900

e, V = (8 x 10 x 1/2) x 60 = 2400

f, V = (8 x 10 x 1/2) x h = 40 x h

Hope this helps!

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
