The diagram represents a model of a ramp the skateboard club wants to create at the neighborhood skate park. If one pint of paint covers 200 square inches, how many pints of paint will the club need to purchase? Paint is only sold in whole pints.
To find the total area of the ramp, we need to find the area of each individual section and then add them together.
Area of Square 1 = 20 in x 20 in = 400 sq in
Area of Square 2 = 10 in x 10 in = 100 sq in
Area of Rectangle 1 = 30 in x 10 in = 300 sq in
Area of Rectangle 2 = 40 in x 10 in = 400 sq in
Total area = 400 sq in + 100 sq in + 300 sq in + 400 sq in = 1200 sq in
Now, we can calculate the number of pints of paint needed:
1200 sq in ÷ 200 sq in/pint = 6 pints
Therefore, the skateboard club will need to purchase 6 pints of paint.
