To find the surface area of a rectangular prism, you need to calculate the areas of all six faces and then add them together.

The formula for the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh

Given that the rectangular prism has sides of length 3 inches, 5 inches, and 12 inches, we can plug these values into the formula:

Surface Area = 2(3*5) + 2(3*12) + 2(5*12)
Surface Area = 2(15) + 2(36) + 2(60)
Surface Area = 30 + 72 + 120
Surface Area = 222 square inches

Therefore, the surface area of the rectangular prism is 222 square inches.

To find the surface area of a cube, you need to calculate the areas of all six faces and add them together. Since a cube has all sides of equal length, the surface area formula simplifies to:

Surface Area = 6s^2

Given that the cube has a side length of 1.5 inches, we can plug this value into the formula:

Surface Area = 6(1.5)^2
Surface Area = 6(2.25)
Surface Area = 13.5 square inches

Therefore, the surface area of the cube is 13.5 square inches.
