Alberto is painting a large triangle on one wall of his bedroom the base of the triangle is 4ft and height is 8ft it takes 0.2 quart of paint to cover 1 square foot
A= 1/2 * b * H
1/2 * 4 * 8 = 16 square feet
Then multiply the area by how many quarts covers 1 square foot.
16 * 0.2 = 3.2
Your Answer is 3.2 quarts
To find out how much paint Alberto needs to cover the entire triangle, you can follow these steps:
Step 1: Calculate the area of the triangle.
The formula for finding the area of a triangle is:
Area = (base * height) / 2
In this case, the base of the triangle is 4ft and the height is 8ft. Plugging these values into the formula:
Area = (4 * 8) / 2 = 32 square feet
Step 2: Determine the amount of paint needed per square foot.
We're given that it takes 0.2 quart of paint to cover 1 square foot.
Step 3: Calculate the total amount of paint required.
To find the total amount of paint needed, multiply the area of the triangle by the amount of paint needed per square foot:
Total paint = Area * Amount of paint per square foot
Total paint = 32 square feet * 0.2 quart/square foot = 6.4 quarts
Therefore, Alberto needs 6.4 quarts of paint to cover the entire triangle on the wall.
Area = bh/2
Amt Paint = bh/2(.2) quarts
Insert values and calculate.
