Question

A gallon of latex paint can cover 600 square feet. Maria has a rectangular room whose dimensions are 23 feet by 10 ​feet, with 7​-foot ceilings. How many gallon containers of paint does she need to buy to paint two coats on each​ wall?

Answer 1

Answer: 3,220

Step-by-step explanation: What you do first is find the volume of the room which is 1,610. So after that you multiply 1,610 by 2 since Maria wants "two" coats of paint on each wall.

Answer 2

1.54 gallons of paint.

Explanation:

Maria has a rectangular room whose dimensions are 23 feet by 10 feet, with 7 feet ceilings.

Area = 2(length + width) × height

= 2( 23 + 10)× 7

= 2 × 33 × 7

= 462 feet²

Total area of the room that she has to paint is 462 square feet. She wants to paint two coat on each wall.

Now the area would be 462 × 2 = 924 square feet

A gallon of latex paint can cover 600 square feet.

to paint 924 feet² she needs =
`(924)/(600)`

= 1.54 gallons of paints.

She needs to buy 1.54 gallons of paint.
