Answer:
234ft²
Step-by-step explanation:
Surface of the triangular prism
= ab+3bh
= (6ft×13ft)+(3×13ft×4ft)
= 78ft²+156ft²
= 234ft²
Hence, the surface area of the given triangular prism is 234ft².
The cross-section of a sphere is a circle . The area of a circle can be calculated by the formula A= 
Where r is the radius of the circle.
Given :
Solving for r we have:
Or r= 10.
The area of a sphere is calculated by the formula :
Substituting r value we have:
SA= 
The total surface area of this sphere is 400π .
