The surface area of the rectangular prism can be found by calculating the surface area of each individual face and summing them up.
Surface Area of the top and bottom faces (length x width) = 2(12 in x 5 in) = 2(60) = 120 square inches
Surface Area of the front and back faces (length x height) = 2(12 in x 3 in) = 2(36) = 72 square inches
Surface Area of the right and left faces (width x height) = 2(5 in x 3 in) = 2(15) = 30 square inches
Total surface area = 120 + 72 + 30 = 222 square inches
Therefore, the surface area of the rectangular prism is 222 square inches.

The surface area of a cube can be calculated by finding the area of all 6 faces.
Each face of the cube is a square with side length equal to the side of the cube. Therefore, the surface area of the cube is given by:
Surface Area = 6 * (side length)^2
Given that the side length of the cube is 1.5 meters, we can plug in the value:
Surface Area = 6 * (1.5)^2
Surface Area = 6 * 2.25
Surface Area = 13.5 square meters
Therefore, the surface area of the cube is 13.5 square meters.
