The surface area of a rectangular prism can be calculated by adding the areas of all of its six faces. The formula to calculate the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
where l = length, w = width, and h = height.
In this case, the rectangular prism has a base of 12 and a height of 1.5. Assuming the base is the length and width dimensions, we can substitute these values into the formula:
Surface Area = 2(12)(1.5) + 2(12)(1.5) + 2(1.5)(12)
Surface Area = 2(18) + 2(18) + 2(18)
Surface Area = 36 + 36 + 36
Surface Area = 108
Therefore, the surface area of the rectangular prism is 108 square units.
base = 12
height = 1.5
