Airida [17]

Answer:

  • 10.7 liters of paint required

Step-by-step explanation:

Dimensions of the room

  • 7.7 m by 14.8 m with the height of 2.4 m

Find the surface area of the 4 walls

  • A = Ph = 2(l + w)h = 2(7.7 + 14.8)*2.4 = 108 m²

Convert the area to ft²

  • 108 m² = 108*10.7639 ft² = 1162.5012 ft²

Find the amount of paint required

  • 1162.5012/410 = 2.84 gal (rounded)

Covert the volume to liters

  • 2.84 gal = 2.84*3.76 l = 10.7 l (rounded)
