Answer:
629 is the length
Step-by-step explanation:
Just plug in your numbers to the formula.
s = [tex]\sqrt{\frac{3V}{h} }[/tex] Plug in.
[tex]s = \sqrt{\frac{3*7700000}{146} }[/tex]
s = [tex]\sqrt{1582191.781}[/tex]
s = 1257.852051
plug in
V = 1/3(1257.852051)²146
Base = s = l*w
s/2 = 628.92 ≈ 629
I'm not 100% but hope this helps!
