An open, rectangular box with length of 6 feet, width of 4 feet and height of 2.5 feet is to be painted on all exterior sides, including the bottom, with a special waterproof coating. Each gallon of this special coating covers 12 square feet of surface area and costs $36.00. The box is then filled with water that weighs approximately 62 pounds per cubic foot?

Painting involves surface area
The box is made of rectangles -
how many rectangles?
What are the surface area of the each of the rectangles.
What is the total surface area?
How many gallons of paint will be needed? (Each gallon of this special coating covers 12 square feet of surface area and costs $36.00) and what's the cost?

So what's that doing in the problem? Get box's volume?
