Answer:
192 
Step-by-step explanation:
Given that
Volume of spherical sculpture = 256 ft³
is used as 3.
To find:
Surface area of sculpture = ?
Solution:
First of all, let us learn about the formula for Volume and Surface Area of Sphere:
1. 
2. 
Given volume is 256 ft³.

Now, let us put r = 4 in the formula of Surface Area to find the value of Surface Area:

So, approximate surface area of sculpture is 192
.
