Answer:
The surface area of this rectangular prism is 324 [tex]inches^{2}[/tex].
Step-by-step explanation:
The formula for surface area of a rectangular prism is this :
A = 2(wl + hl + hw)
l = 6, w = 5, h = 12.
Now knowing these values, we can solve for A.
A = 2(wl + hl + hw) = 2(5 · 6 + 12 · 6 + 12 · 5) = 324
The surface area of this rectangular prism is 324 [tex]inches^{2}[/tex].
