Paul wants to paint all four of his basement walls. each gallon covers 400 square feet. the dimensions of the basement are 25’ by 30’. the walls are 8’ high. how many gallons of paint will paul need to complete the job if he is only painting one coat?

Paul need 2.2 gallons of paint to complete his job.

Step-by-step explanation:

We are given the dimensions of the basement as,

Length = 25 feet, Width = 30 feet and Height = 8 feet .

Since, Paul wants to paint only the walls of the basement.

So, the dimensions of the walls are, 25' × 8' and 30' × 8'.

As, we know, Area of a rectangle = Length × Width

And there are 2 walls of each 25' × 8' and 30' × 8' dimension.

We get,

Area of the walls = 2(25× 8+ 30 × 8)

i.e. Area of the walls = 2(200+240)

i.e. Area of the walls = 2 × 440

i.e. Area of the walls = 880 feet²

Since, 400 feet² is covered by 1 gallon.

Then, 880 feet² is covered by = 2.2 gallons.

Hence, Paul need 2.2 gallons of paint to complete his job.
