A 0.500m long hexagonal concrete shaft measuring 20.0cm across the corners has a triangular hole running lengthwise from end to end (Fig 6-36). The triangular hole is an equilateral triangle with sides 10.0cm long. What is the total surface area of the shaft?

FIGURE 6-36
Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).
