Answer:
the cylinder container has the greatest surface area.
Step-by-step explanation:
The volume of cone is calculated by 
The volume of cylinder is calculated by 
The volume of square pyramid is calculated by 
The volume of rectangular prism is calculated by 
The radius of cone is
=
, and slant height is 10 in.
height is calculated as h² = l²- r²
h² = l²- r²
h² = 10²- 3²
h² = 100- 9
h² =91
h= 9.54
The volume of cone is 

<u>v=89.8668</u>
The volume of cylinder is 

<u> v=282.6</u>
The volume of square pyramid
The height of pyramid is calculated as h² = l²- r²
h² = 10²- 3²
h² = 100- 9
h² =91
h= 9.54



The volume of rectangular prism

Hence, the cylinder container has the greatest surface area.
