When you have to describe a 3D shape you have to keep the following definitions in mind:

<em>1. The face of a 3D shape is a flat surface.</em>

The shape on the picture has 3 rectangular faces and 2 triangular faces, a total of 5 faces.

<em />

<em>2. The edge is where two faces meet.</em>

For the shape on the picture, there are 3 edges, where the rectangular faces meet each other, and then three edges where the rectangular faces meet each of the triangular faces, this shape has a total of 9 edges.

<em>3. The vertex is a corner, where the edges meet.</em>

There are three vertices on each end of the shape, so it has a total of 6 vertices.

A shape that has 5 faces, 9 edges, and 6 vertices is a triangular prism.

two years of local internet service cost $685 including the installation fee of $85 what is the monthly fee?
zimovet [89]
2 years is the same as 24 months, so the equation would be:
685 = 24x + 85, where x is the monthly fee.
600 = 24x
600/24 = x
x = 25
The monthly fee is $25.
