Answer:

$360\ cm^2$

Explanation:

Step 1: Determine the area of the bottom rectangle

A = l * w

$A = 10\ cm * 12\ cm$

$A = 120\ cm^2$

Step 2: Determine the area of the back rectangle

A = l * w

$A = 10\ cm * 5\ cm$

$A = 50\ cm^2$

Step 3: Determine the area of the top rectangle

A = l * w

$A = 10\ cm * 13\ cm$

$A = 130\ cm^2$

Step 4: Determine the area of the triangle

A = (h*b)/(2)

$A = (5\ cm * 12\ cm)/(2)$

$A = (60\ cm^2)/(2)$

$A = 30\ cm^2$

Step 5: Determine the surface area

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

$360\ cm^2$

Answer:
$360\ cm^2$
