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.
Because you're starting the company with 4 friends, there are 5 people in total. Therefore, if you do (400 × 5) + 525, you get the answer. 400 × 5 = 2000, and 2000 + 525 = $2525. I hope this helps! Let me know if you need me to explain anything :)
Answer:
625b^6
Step-by-step explanation:
= 5^3 * 5b^6
= 5^3 * 5
= 625
