The Space and Shape of the Six-year Special Training Paper of Rongdeji Primary School Series Good Volume Mathematics (2)
Let two angles of triangle AB be 2a and BC be 3a.
The volume of a cone with AB as its side is v = 1/3π (3a) 2 * 2a = 6a 3π.
The volume of a cone with BC as its side is v = 1/3π (2a) 2 * 3a = 4a 3π.
