The diagram represents a model of a ramp the skateboard club wants to create at the neighborhood skate park. If one pint of paint is 200 square inches. How many pints of paint will the club need to purchase? Paint is only sold in whole pints

Answer 1

To find the total square inches that need to be painted, we need to calculate the area of the ramp.

Looking at the diagram, the ramp can be split into two sections - a rectangle and a triangle.

The rectangular section:
Length = 20 inches
Width = 8 inches

Area of rectangle = Length x Width
Area of rectangle = 20 inches x 8 inches
Area of rectangle = 160 square inches

The triangular section:
Base = 12 inches
Height = 8 inches

Area of triangle = (Base x Height) / 2
Area of triangle = (12 inches x 8 inches) / 2
Area of triangle = 96 square inches

Total area = Area of rectangle + Area of triangle
Total area = 160 square inches + 96 square inches
Total area = 256 square inches

Therefore, the club will need to purchase:
256 square inches ÷ 200 square inches per pint = 1.28 pints

Since paint is sold in whole pints, the club will need to purchase 2 pints of paint.
