She will need material to cover the six faces
Two faces each are similar
so that the two opposite sides have similar areas
Area of one = length x breadth = 10 x 6 = 60 square inches
for both similar areas = 60 x 2 =120 square inch
Area of 2 = Length x breadth =6 x 5 = 30 square inches
for both similar areas = 30x 2 = 60 square inches
Area of 3 = Length x breadth = 10 x 5 = 50 square inches
for both similar areas = 50 x 2 = 100 square inches
Total area = 120+ 60 +100 = 280 square inches
