To make a 1.1-meter-long, 6-decimeter-wide and 9-decimeter-high uncovered rectangular iron sheet water tank, how much area of iron sheet is needed? What is the volume of the water tank? To make a 1.1-meter-long, 6-decimeter-wide and 9-decimeter-high uncovered rectangular iron sheet water tank, how much area of iron sheet is needed? What is the volume of the water tank? (regardless of the thickness of the iron sheet)
1.1 m = 11 decimeters
Area = 11x6 + (11x9 + 6x9) x2 = 66 + (99 + 54) x2 = 66 + 153x2 = 66 + 306 = 372 square decimeters
Volume = 11x6x9 = 66x9 = 594 cubic decimeter
