The explanation is the picture. Β I hope this answers your question.
welp
ok so first what you do is you find out which sides have the smallest and largest surface areas
largest: 50x5 (250in)
smallest: 5x3 (15in)
what you would do if you wanted the smallest surface is you would glue the 50x5 surfaces together like this: |_| if the 5in sides are facing to the side
smallest like this: ||| if the 5in sides are facing to the side
CALCULATE:
50*5+53*5+53*5+3*5+3*5+50*5+50*5+47*5+2*5*10*3*3
simplifies to:
489*5
2445
LARGEST SURFACE AREA
CALCULATE:
9*5+9*5+50*5+50*5+9*5*10+9*5*10
simplifies to:
289*5
1445
SMALLEST SURFACE AREA
