Answer:
C.
Step-by-step explanation:
Base area = 9 × 13
= 117 square feet
Now
Volume of pyramid = (1/3)(A)(H)
= (1/3)(117)(30)
= 117 × 10
= 1170 cubic feet
The number of triangles is n-2
n= number of sides
8-2= 6 triangles
if applying this you won't have to draw any diagonals to
find the number of triangles just subtract 2 from the number of sides
hope this helps
