there are two boxes connected the Hight of the first box is 8mm the height of the second box is 6mm the width of the the first box is 10mm the width of the second on is 6mm the lenght of both of them is 6mm. so what is the the total sufrface area

Answer 1

First box:
Surface area = 2lw + 2lh + 2wh
Surface area = 2(10*6) + 2(10*8) + 2(6*8)
Surface area = 284 mm^2

Second box:
Surface area = 2lw + 2lh + 2wh
Surface area = 2(6*6) + 2(6*8) + 2(6*6)
Surface area = 192 mm^2

Total surface area = Surface area of first box + Surface area of second box
Total surface area = 284 + 192
Total surface area = 476 mm^2

Therefore, the total surface area of both boxes connected is 476 mm^2.
