We know that Area of steel metal = Total cost / Cost per m2By substituting valuesArea of sheet metal =1206480​So we getArea of sheet metal =54 m2So we getArea of sheet metal =2(1b+bh+h1)54=2(5×3+3× h+h× 5)On further calculation 27=15+3h+5hSo we get8h=12By divisionh=1.5mTherefore, the height of sheet metal is 1.5m
