We know that
[volume of the triangular prism]=[area of the base]*height
area of the base=15*3/2-----> 22.5 in²
height of the prism=16 in
so
[volume of the triangular prism]=[22.5]*16------> 360 in³
the answer is
the volume of the triangular prism is 360 in³
Answer:


Step-by-step explanation:










sum of all 3 angles inside a triangel is 180
first subtract the last equation from the first. this gives:-
-x + y = -8 .....................(1)
Then multiply the first equation by 2 and add it to the 2nd equations This gives
9x = 18
so x = 2
and from equation (1) y = -8 + 2 = -6
Substituting for x and y in the second equation
z = (24 -5(2) -12) / 2 = 1
Answer is choice b.
