The surface area of rectangular prism is 396 [tex]inch^{2}[/tex]
What is rectangular prism?
In geometry, a rectangular prism can be defined as a 3-dimensional solid shape which has six faces that are rectangles. A rectangular prism is also a cuboid.
According to the question,
Length of rectangular prism(l) = 7 inch
Height of rectangular prism(h) = 12 inch
Width of rectangular prism(w) = 6 inch
Given formula of Surface area = 2lw + 2lh + 2wh
= 2×7×6 + 2×7×12 + 2×6×12
= 84 + 168 + 144
= 396 [tex]inch^{2}[/tex]
Hence, the surface area of prism = 396 [tex]inch^{2}[/tex]
