Sagot :

Answer:

320 square inches

Explanation:

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

[tex]S=2(lw+wh+lh)[/tex]

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:

[tex]\begin{gathered} S=2\lbrack(12\times4)+(4\times7)+(12\times7)\rbrack \\ S=2(48+28+84) \\ S=2(160) \\ S=320in^2 \end{gathered}[/tex]

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