Answer:
It’s a square-based pyramid
base(1) is the square on the bottom- ABCD
Faces(4) are the triangles on the sides eg- AED, DEC, CEB, BCA
There are 8 edges, four being at the bottom around the base and the other four being alone the faces
Finally there are 5 vertices, four being at the corners of the base and the fifth being the tip of the pyramid

Answer: it is th
Step-by-step explanation:
We know that
[volume of a square pyramid]=area of the base*height /3
area of the base=3*volume/height
volume=245 in³
height=15 in
area of the base=3*245/15-------> 49 in²
the area of the base is a square
so
area=b²---------> b=√area---------> b=√49-------> b=7 in
the answer is
T<span>he length of one side is 7 in</span>
Answer:14
