Answer:
Vol B/A = 27
Step-by-step explanation:
The volume of a square pyramid is given by:
V = (1/3)a^2h
where a is the lenght of a base side.
In this question, we have:
Pyramid A
a = 12"
h = 8"
Volume A = (1/3)(12)^2*(8)
Volume A = 384 in^3
Pyramid B
a = 36"
h = 24"
Volume B = (1/3)(36)^2*(24)
Volume B = 10368 in^3
Ratio of Volumes B/A = 10368/384
B/A Vol Ratio = 27
I'll take pyramid B.
