Answer:


S = 276\ in^2

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 →
S= 2(wl+hl+hw)

Step 2: Plug in the values and solve


S = 2((10\ in * 4\ in) + (7\ in * 4\ in) + (7\ in * 10\ in))


S=2(40\ in^2 + 28\ in^2 + 70\ in^2)


S = 2(138\ in^2)


S = 276\ in^2

Answer:
S = 276\ in^2
