Given l = 90,b=40,h=50cm.
Bottom Area = l * b = 3600 sq.cm
Side face area = b * h = 40 * 50 = 2000
Back face area = l * h = 90 * 50 = 4500.
Area of the paper needed = 3600 + 4500 + 2(2000)
= 12100 sq.cm.
Bottom Area = l * b = 3600 sq.cm
Side face area = b * h = 40 * 50 = 2000
Back face area = l * h = 90 * 50 = 4500.
Area of the paper needed = 3600 + 4500 + 2(2000)
= 12100 sq.cm.
