Answer:

360\ cm^2

Step-by-step explanation:

<u>Step 1:  Determine the area of the bottom rectangle</u>

A = l * w

A = 10\ cm * 12\ cm

A = 120\ cm^2

<u>Step 2:  Determine the area of the back rectangle</u>

A = l * w

A = 10\ cm * 5\ cm

A = 50\ cm^2

<u>Step 3:  Determine the area of the top rectangle</u>

A = l * w

A = 10\ cm * 13\ cm

A = 130\ cm^2

<u>Step 4:  Determine the area of the triangle</u>

A = \frac{h*b}{2}

A = \frac{5\ cm * 12\ cm}{2}

A = \frac{60\ cm^2}{2}

A = 30\ cm^2

<u>Step 5:  Determine the surface area</u>

120\ cm^2 + 50\ cm^2 + 130\ cm^2 + 2(30\ cm^2)

360\ cm^2

Answer: 360\ cm^2
