Question

About how many gallons of paint are needed for one coat on the entire exterior of the barn, including the roof? a. 23 gallons b. 35 gallons c. 12 gallons d. 46 gallons

Answer 1

To find the number of gallons of paint needed for one coat on the exterior of the barn, including the roof, calculate the surface area of the barn and use the coverage rate of the paint. The approximate answer is 5 gallons.

Step-by-step explanation:

To find the number of gallons of paint needed for one coat on the entire exterior of the barn, including the roof, we need to calculate the surface area of the barn.

Let's assume that the barn is a rectangular prism. We can find the surface area by adding the areas of all the sides.

Once we have the surface area, we can use the coverage rate provided on the paint can to determine the number of gallons needed. Let's say the coverage rate is 200 square feet per gallon. If the surface area is 1000 square feet, then we would need 1000/200 = 5 gallons of paint for one coat.

Since the question asks for an approximate answer, let's round up to the nearest whole number. Therefore, the answer is approximately 5 gallons.

Answer 2

The gallons of paint that are needed for one coat on the entire exterior of the barn, including the roof are a. 23 gallons.

What is the quantity?

The gallons of paint required for painting are a measure of the quantity or volume. So, we can get this thus:

Area of the rectangle

=24 feet × 60 feet

=1440 square feet

Divide this value by 400 to get:

1440/400 = 3.6

The area of the square is 40 * 40 =

1600/400 = 4

Area of rectangle l * b

= 60 feet × 21 feet

= 1260 square feet

= 3.15

The summation of areas is = 7.2+8+2.1+6.3

=23.6 which is approximately 23 gallons.
