Manny is painting 5 cubes that are each 2 inches long. He needs to paint each cube twice. How much surface area total will he paint?
6 sides each
4 sq.in / side
5 cubes
2 coats of paint
6 * 4 * 5 * 2 = 240 square inches
240
To find the total surface area that Manny will paint, we need to calculate the surface area of one cube and then multiply it by the number of cubes and the number of times it needs to be painted.
The surface area of a cube can be found using the formula: 6 * (side length)^2.
In this case, the side length of each cube is 2 inches. So, the surface area of one cube is:
6 * (2 inches)^2 = 24 square inches.
Since Manny needs to paint each cube twice, we multiply the surface area of one cube by 2.
Total surface area painted = 24 square inches * 2 = 48 square inches.
Therefore, Manny will paint a total surface area of 48 square inches.
