Step-by-step explanation:
Total height of the stairs = 120 cm
Total standing stairs = 4

= 30 cm
Length of every stair has = 100 cm
Every horizontal and vertical stair has the same area.
Area of one stair = Length × Width
= 100 × 30
= 3000 cm square
There are 4 horizontal and 4 vertical similar stairs to be painted in gold.
Total area to be painted in gold = 8 × Area of one stair

= 24000 cm²
Total area to be painted in gold = 24000 cm²
