432/9 = b
the base dimensions are 48 in^3
it has rotational symmetry about the origin.
if we rotate it 180 degrees about the origin we get the same graph.
another rotation of 180 degrees also gives the same graph, so we have a rotational symmetry of 2.
if a coin has two sides x and y the chance of it landing on x would be half.
out of 5 flips 2.5 would b x.
you cant land a coin on a half and so the answer would be 2 or 3 if you round up or down.
