Answer: 
- Total surface area of cylinderal can is 150.8 cm²
<u>Step-by-step </u><u>explanation</u><u>:</u><u> </u>
Given that a cylinderal can has base with a diameter of 6 cm and its height measures 5 cm.
So, 
Radius = Diameter/2 = 6/2 = 3 cm
We know that,
- TSA of cylinder = 2πr(h + r) 
Substituting required values:
➝ TSA = 2 × 22/7 × 3(5 + 3) 
➝ TSA = 44/ 7 × 3 × 8 
➝ TSA = 1056/7
➝ TSA = 150.8 cm² 
Hence, 
- <u>Total </u><u>surface </u><u>area </u><u>of </u><u>cylinderal</u><u> </u><u>can </u><u>is </u><u>1</u><u>5</u><u>0</u><u>.</u><u>8</u><u> </u><u>cm²</u>
 
        
                    
             
        
        
        
Number of different bases for each one:
1 1 12 --->1 1 12, 1 12, 1 ----- 2 of them
1 2 6 ---> 1 2 6, 1 6, 2, 2 6 1 --- 3 of them
1 3 4 ---> 1 3 4, 1 4 3, 3 4 1 --- 3 of them
2 2 3 ---> 2 2 3, 2 3 2 ----- 2 of them
Answer-10 different prisms
