(a)
Thelength of diagonal AB.
Answer to Problem 1A
The length of diagonal AB is
Explanation of Solution
Given information:
The dimensions of rectangular solid block are
Calculation:
To calculate the length of diagonal AB, the length of side BC is required. Let us consider the triangle BDC, the angle D of the triangle is a right-angle, so the triangle BDC is a right-angle triangle.
In triangle BDC, the length of side BC can be calculated from Pythagorean theorem.
Let us consider the triangle ABC, the angle C of the triangle is a right-angle, so the triangle ABC is a right-angle triangle.
In triangle ABC, the length of side AB can be calculated from Pythagorean theorem.
Conclusion:
Thus, the true length of diagonal AB is
