Area of the base: A = 6 * 5 /2 = 15

Height: h = 4

V = Ah/3 = 20 u³

Let ABCDEFGH be a rectangular prism, where EF = 4, EH = 5, and EA = 6. Find the volume of the pyramid CFAH.

All the sides (including the base) are congruent.

The lengths of the sides are: ( ≈ ) 6.403, 7.211, and 7.81

Area of the base A ≈ 21.6564 u²

Height of the pyramid h ≈ 5.5456

The volume of the pyramid CFAH V = 1/3 * Ah ≈ 40.033 u³
