You are painting all four walls of a shed. each wall is a rectangle with a length of 14 feet and a height of 8 feet. a gallon of paint covers about 350 square feet. how many gallons of paint do you need in order to cover the walls? write your answer as a decimal.

number of gallons  to cover 4 walls= 1.28  gallons

Step-by-step explanation:

The walls are four in number. Each wall is rectangular in shape. The length of each wall is 14 feet and the height is 8 feet. A gallon of paint will cover an area of 350 square feet. For each wall, the area can be computed since the height and the length is known.

Area of each wall(rectangle) = Length × height

length = 14 feet

height = 8 feet

Area of each wall(rectangle) = 14 × 8

Area of each wall = 112 square feet

The total square feet is 112 × 4 walls

total square feet of the 4 walls = 448  square feet

Since, 1 gallon will  cover 350 square feet

? gallons will cover 448 square feet

cross multiply

number of gallons = 448/350

number of gallons  to cover 4 walls= 1.28  gallons

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
