Answer:

Triangular Pyramid

30.5 cm^3 (cubic centimeters)

Step-by-step explanation:

a shape made up of four triangles is a triangular pyramid.  

Volume of any pyramid is (1/3)*Area of the base*height.

area of the base, or any face, is 17.6 as said in the question, now the height.  is 5.2 so we can solve then.  

V = 1/3 * 17.6 * 5.2 = 30.5
