Chapter 12.1, Problem 20WE

To determine

To draw: the prism.

Explanation of Solution

Given information:

Base is isosceles trapezoid with bases $10\text{ and 4}$ and legs $5$ , $h=20$

Graph: the isosceles trapezoid with bases $10\text{ and 4}$ and legs $5$ , $h=20$

Now to draw a prism first make its base as a triangle and then sketch the length of $10$ triangle from its each point,

Thus, the prism can be obtained as:

  

Interpretation: form the above graph and side and height it can be observed that the lateral area of the prism is $560$ and total area is $640$ and volume is $800$ .
