Truncated Icosahedron - Area and Volume

Area and Volume

The area A and the volume V of the truncated icosahedron of edge length a are:

\begin{align} A & = \left ( 20 \cdot \frac32\sqrt{3} + 12 \cdot \frac54\sqrt{ 1 + 2/\sqrt{5}} \right ) a^2 \approx 72.607253a^2 \\ V & = \frac{1}{4} (125+43\sqrt{5}) a^3 \approx 55.2877308a^3. \\ \end{align}

Famous quotes containing the words area and/or volume:

    “The area [of toilet training] is one where a child really does possess the power to defy. Strong pressure leads to a powerful struggle. The issue then is not toilet training but who holds the reins—mother or child? And the child has most of the ammunition!”
    —Dorothy Corkville Briggs (20th century)

    “To be thoroughly conversant with a Man’s heart, is to take our final lesson in the iron-clasped volume of despair.”
    —Edgar Allan Poe (1809–1845)
