Answer:
[tex]S = 276\ in^2[/tex]
Step-by-step explanation:
Step 1: Determine important information
Using the given numbers it doesn't really matter which is which because the equation multiplies everything together.
Surface Area of a Rectangular Prism → [tex]S= 2(wl+hl+hw)[/tex]
Step 2: Plug in the values and solve
[tex]S = 2((10\ in * 4\ in) + (7\ in * 4\ in) + (7\ in * 10\ in))[/tex]
[tex]S=2(40\ in^2 + 28\ in^2 + 70\ in^2)[/tex]
[tex]S = 2(138\ in^2)[/tex]
[tex]S = 276\ in^2[/tex]
Answer: [tex]S = 276\ in^2[/tex]
