The containers must be spheres of radius = 6.2cm
<h3>How to minimize the surface area for the containers?</h3>
We know that the shape that minimizes the area for a fixed volume is the sphere.
Here, we want to get spheres of a volume of 1 liter. Where:
1 L = 1000 cm³
And remember that the volume of a sphere of radius R is:
Then we must solve:
The containers must be spheres of radius = 6.2cm

2560000 sequences of answers are possible.
<em><u>Explanation</u></em>
Total number of questions = 10
First 4 questions have 5 choices each and remaining (10-4)= 6 questions have 4 choices each.
So, the possible sequences of answers for first 4 questions
and the possible sequences of answers for remaining 6 questions
Thus, the total possible number of sequences of answers = (625 × 4096) = 2560000
