Answer:
4410
Step-by-step explanation:
A=Px(1+R)^n
4000x(1+0.05)^2=4410
64,000 I believe. What I did was find the area so 4*4 =16. 1000/16 = 62.5 earthworms per square foot. So if the side is 8 times longer then 8*4= 32 feet per side and to find the area of that it's 32*32 = 1024 feet squared. So 62.5 * 1024 =64,000
The answer to this question is 0.
Hope this helps :)
