Step-by-step explanation:
Given,Length of cubical box(a) = 30 cm.
Total surface area of the box = 6a²
= 6(30)²
= 5400 cm².
Given that It has to be painted inside and outside the box.
Area = 2 * Total surface area
= 2 * 5400
= 10800 cm²
= 1.08 m².
Given that Rate of painting per m² = 5.50.
For 1.08 m²,cost of painting = 5.50 * 1.08
