Aubrey is painting a mural of an ocean scene. The triangular sail on a sailboat has a base of 4 feet and a height of 6 feet. Aubrey will paint the sail using a special white paint. A can of this paint covers 10 square feet. How many cans of white paint will Aubrey need?
A = 1/2 * b * h
Divide the area by 10 to find the number of cans. Round up to the next whole number.
2 cans or 1 1/5 cans. Hope this will help!
Basically first you multiply 6 with 4 and you get 24. Than you divide 24 by 2 and you get 12. After that, you divide 12 by 10 and get 1.5. Aubrey can’t 1.5 because she can’t get a half can of white paint so she has to get 2. Hopefully this helped, thanks for stoping by and check this answer out!
To determine the number of cans of white paint Aubrey will need, we need to calculate the area of the triangular sail and then divide it by the coverage of one can of paint.
The formula to find the area of a triangle is:
Area = (base * height) / 2
In this case, the base of the triangular sail is 4 feet and the height is 6 feet. Let's substitute these values into the formula:
Area = (4 * 6) / 2
Area = 24 / 2
Area = 12 square feet
Now, we know that one can of white paint covers 10 square feet. To find the number of cans Aubrey will need, we need to divide the area of the sail by the coverage of one can:
Number of cans = Area of sail / Coverage per can
Number of cans = 12 square feet / 10 square feet
By performing the division, we find:
Number of cans = 1.2 cans
Since we can't buy a fraction of a can, we need to round up. Therefore, Aubrey will need 2 cans of white paint for her mural.
