Gr 11 Math Lit: Ch 2.1 Conversions

What is the purpose of calculating the paint required based on the surface area and the spread rate of the paint?

To determine the best type of paint to use
To determine the cost of the paint
To determine the amount of paint needed (correct)
To determine the time it takes to paint the surface

What is the formula to calculate the total liters of paint needed?

Paint Needed (liters) = Surface Area (m²) ÷ Spread Rate (m²/liter) (correct)
Paint Needed (liters) = Surface Area (m²) - Spread Rate (m²/liter)
Paint Needed (liters) = Surface Area (m²) + Spread Rate (m²/liter)
Paint Needed (liters) = Surface Area (m²) × Spread Rate (m²/liter)
