Question

A painter was assigned to paint the sides of a building of sides 10m by 8m by 3.5m. If the cost of painting a square meter is $4.50, calculate the cost of painting the building

Answer 1

To calculate the cost of painting the building, you need to find the surface area and multiply it by the cost per square meter. The total cost is $1287.

Step-by-step explanation:

To calculate the cost of painting the building, we need to first calculate the total surface area that needs to be painted. The building has dimensions of 10m by 8m by 3.5m.

Surface Area = 2 * (Length * Width + Length * Height + Width * Height)

Surface Area = 2 * (10 * 8 + 10 * 3.5 + 8 * 3.5) = 2 * (80 + 35 + 28) = 2 * 143 = 286m²

Now, we can calculate the cost of painting the building:

Cost = Surface Area * Cost per square meter

Cost = 286 * $4.50 = $1287
