Answer:
339604.65 cubic feet
Step-by-step explanation:
We are given that 1 m is equal to 3.3 ft.
1 m = 3.3 ft
This means that if we find the volume of a cube of 1 m, we have its volume as:
In the same way, the volume of a cube of 3.3 ft (1 m) is:
This means that:
The Kuroshio sea tank has volume of . Its volume in cubic feet is therefore:
The volume of the tank is 339604.65 cubic feet.
V of w sphere = 
r³
Multiply by 3 on either sides to get rid of the fraction.
3V = 4r³
Now divide either sides by 4 to isolate r³
r³
4
and 4 cancels out
= r³
Take the cube root to isolate r.
![\sqrt[3]{ \frac{3V}{4 \pi } } = \sqrt[3]{r^3}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B3V%7D%7B4%20%5Cpi%20%7D%20%7D%20%3D%20%20%5Csqrt%5B3%5D%7Br%5E3%7D%20)
the cube root cancels the cube

= r
Multiply by 3 on either sides to get rid of the fraction.
3V = 4
Now divide either sides by 4
4
Take the cube root to isolate r.
