Answer:
45 in
Step-by-step explanation:
Base area of a square pyramid is given by
B=a*a=a²
Where a is the length of each side of the base
Volume of a square pyramind is given by
V=⅓Bh
Where h is the height
Given that height is 1.5a then B is a²
V=⅓*a²*1.5a=0.5a³
Given that the volume is 4500 in³
0.5a³=4500
a³=9000
a=3√9000=30
Since height is 1.5a then h=1.5*30=45 in
