Answer:
(a) Rectangle
Step-by-step explanation:
Given
See attachment for cube
Solving (a): Cross-section formed when lines AC and EH meets
Lines AC and EH will meet midway of lines AE and CH
So, the shape that will be formed is quadrilateral and the sides of the quadrilateral is: AE, EH, HC and CA
Where
CA is the diagonal of the top face of cube.
So:
So, we have:
Take square roots
So, we have:
<em>The cross-section is a rectangle</em>
Solving (b): The area of the cross-section
Solving (c): How the cross-section is determined
<u>Copied from (a)</u>
<em>Lines AC and EH will meet midway of lines AE and CH</em>
<em>So, the shape that will be formed is quadrilateral and the sides of the quadrilateral is: </em>AE, EH, HC and CA
<em />
I think its C but I cant put the paper work because it involves right it on paper
