No, look at the triangle.

Answer 4

it's been a long time since I have work with these things so ya

Answer 5

uh...24 ?

Answer 6

The base is 24. The length is 30.
\[\large Volume = \frac{ 1 }{ 2 }*base* height*length\]
\[\large 3240= \frac{ 1 }{ 2 }*24* h*30\]
solve for h

Answer 7

h=15 ?

Answer 8

No, show your work.

Answer 9

3240 divided by 1.5 divided by 24 divided by 30 = 3
