A 3-dimensional figure has a square base and 4 lateral faces that meet at a point. Explain the difference between the cross sections when a slice is made perpendicular to the base through the vertex, and when a slice is made perpendicular to the base and not through the vertex.

This figure is a square pyramid. If you have vertical cross sections through the vertex of the pyramid, then you end up with a triangle as figure 1 shows. See the attached image below. Figure 2 shows a trapezoid forms when the vertical cross section is not through the vertex.

this is answer of 144 cubic meters

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
