Question

3 fill blank boxes with the right answer. write an x in the last box, that is a mistake the shape has
blank box vertices
blank box edges
blank box faces blank box

Explanation:

Step1: Count Vertices

A triangular pyramid (tetrahedron) has 4 vertices: 1 apex and 3 base vertices.

Step2: Count Edges

Each of the 3 base vertices connects to the apex (3 edges) and the base is a triangle (3 edges), so total edges = 3 + 3 = 6.

Step3: Count Faces

The base is 1 triangular face, and there are 3 triangular faces connecting the apex to the base, so total faces = 1 + 3 = 4.

Step4: Mark Mistake

The last box (after "faces") gets an X.

Answer:

First box (Vertices): 4
Second box (Edges): 6
Third box (faces): 4
Last box: X
