Answer: To paint a cube with edges of 2 feet each for a math project, Jackie will need 24 square feet of paint.
Step-by-step explanation: A cube has six faces, all of which are squares, and each face has an area of (length of one side)^2. In this case, the length of one side of the square is 2 feet, so the area of each square face of the cube is 2^2 = 4 square feet. Since there are six faces, the total surface area of the cube is 6 x 4 = 24 square feet. Therefore, Jackie will need to buy or have 24 square feet of paint to cover the entire surface area of the cube. It is important to note that this calculation assumes that the paint used has no thickness, and that only one coat of paint is applied. In reality, more paint may need to be used. Hope this helps, and have a great day!
