Question

Lisa wants to cover the outside of this box with fabric for an art project. How much material will Lisa need? Select one: O280 square inches O120 square inches O 300 square inches O60 square inches

Answer 1

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
