Answer:
110 yards^3
Step-by-step explanation:
volume of a triangular pyramid= 1/3 area x height
1/3 x (22) x 15 = 110 yd^3
Steps to solve:
x^3 - 125 = 0
~Add 125 to both sides
x^3 = 125
~Take cube root of both sides
x = 5
Best of Luck!
I think it would be 17.5in
Hope this helps!!
Answer:-30
Third term=a3
an=a(n-1) x (-9)
a3=5/3 x (3-1) x (-9)
a3=5/3 x 2 x -9
a3=(5x2x-9)/3
a3=-90/3
a3=-30
