Answer:
Explanation:
Since the roof is triangular, we would the amount of paint required by determining the surface area of the roof. We would apply the formula for determining the area of a triangle which is expressed as
Area = 1/2 × base × height
From the information given,
Height = 4.6m
Base = 8.8m
Surface area = 1/2 × 8.8 × 4.6 = 20.24m²
if one liter of paint covers 4 square meters, then the amount of paint needed to cover 20.24m² is
20.24/4 = 5.06 liters
It means that 5.06 litres would be required for one coat of paint. The number of litres required for three coats of paint is
5.06 × 3 = 15.18 litres
