(20 14 Taizhou simulation) The three views (unit: cm) of a geometric figure are shown in the figure, so the volume of this geometric figure is equal to _ _ _ _ _ cm3.

From the known three views, we can know that the geometric shape is a quadrangular cone with the front view as the bottom. We can calculate the area and height of the bottom surface of the geometry and substitute it into the pyramid volume formula to get the answer.

Solution: According to the known three views, the geometric shape is a quadrangular cone with the front view as the bottom.

Its bottom surface area s =1/2× (3+1) 2 = 4,

The height of the pyramid h=2,

So the volume of the pyramid V= 1/ 3 S? h=8 /3,

So the answer is: 8/ 3.
