Answer:
The surface area is 240 cm^2
Step-by-step explanation:
The surface area is the sum of all the areas of the shapes present
we have two rectangles of measure 7 cm by 12 cm
A base rectangle of 4 cm by 12 cm
Two side triangles of base 4 cm and height 6 cm
Area of the rectangles is l * b
Area of the triangles is 1/2 * b * h
Thus, we have that;
(7 * 12) * 2 ) + 2 * (1/2 * 4 * 6) + (4 * 12)
= 168 + 24 + 48 = 240 cm^2
