Answer:
The shortest path to take is or
Step-by-step explanation:
<em>This question requires an attachment (See attachment 1 for question)</em>
Given
Cube Dimension: 20cm * 20cm
Required
Shortest path from A to B
For proper explanation, I'll support my answer with an additional attachment (See attachment 2)
The shortest path from A to B is Line labeled 2
But first, the length of line labeled 1 has to be calculated;
This is done as follows;
Since, the cube is 20 cm by 20 cm
(Pythagoras Theorem)
Take square root of both sides
Split square root
Next is to calculate the length of Line labeled 2
(Pythagoras Theorem)
Substitute
Expand the expression
Factorize
Take square root of both sides
Split square root
<em>The answer can be left in this form of solve further as follows;</em>
<em> (Approximated)</em>
<em>Hence, the shortest path to take is </em><em> or </em>
