Question

Faces: Edges: Vertices:

Answer 1

Answer:

$Faces~:~5\\Edges~:~8\\Vertices~:~5$

Concept:

Here, we need to distinguish between face, edge, and vertex (plural: vertices)

A face is a single flat surface

An edge is a line segment between faces

A vertex is a corner

Please refer to the attachment below for a visual understanding

Solve:

Count the number of faces

• One on the bottom
• Four connecting to each side of the square at the bottom

1 + 4 = $\Large\boxed{5~faces}$

Count the number of edges

• Four on the bottom that shape the square
• Four on the sides that shape the triangles

4 + 4 = $\Large\boxed{8~edges}$

Count the number of vertices

• Four on the bottom that surrounds the square
• One on the top where triangles intersect

4 + 1 = $\Large\boxed{5~vertices}$

Hope this helps!! :)
