320 square inches

The formula for finding the surface area of a cuboid is expressed as:

L is the length of the cuboid

W is the width of the cuboid

H is the height of the cuboid

Given the following parameters:

L = 12in

W = 4 in

H = 7 in

Substitute the given parameters into the formula as shown:

$\begin{gathered} S=2\lbrack(12*4)+(4*7)+(12*7)\rbrack \\ S=2(48+28+84) \\ S=2(160) \\ S=320in^2 \end{gathered}$

Hence the surface area of the given shape is 320 square inchess 3
