Really!

anonymous · Answer

volume of prism = length * area of triangular cross section
area of the triangle = (1/2)* height* length of base

anonymous · Answer

so plug in the values given
height  = 15 , base = 24 and length = 30

anonymous · Answer

volume = 30*(1/2)*15*24

anonymous · Answer

sorry I misread the question
we need to find the height 
volume = area triangle * length

3240 =30 *(1/2)*24* h

solve for h
