The formula for surface area of a rectangular prism is 2lw + 2lh + 2wh, where l = length, w = width, and h = height.
Plugging in the values:
2(12)(5) + 2(12)(3) + 2(5)(3)
= 120 + 72 + 30
= 222 square inches
Therefore, the surface area of the rectangular prism is 222 square inches.

The formula for the surface area of a cube is 6s^2, where s is the length of a side.
Plugging in the value:
6(1.5)^2
= 6(2.25)
= 13.5 square meters
Therefore, the surface area of the cube is 13.5 square meters.
