Calculating the Height of a Truck Bed Using the Pythagorean Theorem

Seoers and math enthusiasts alike can find value in understanding the Pythagorean theorem and how it can be applied in real-world scenarios. This article will walk you through a practical application of the theorem in calculating the height of a truck bed using the given measurements and distances.

The Math Problem

The problem given is: A ramp created to get up to a truck bed is 3 meters (m) long. The ramp starts 2.82 meters (m) from the truck. What is the height of the truck bed to the nearest tenth of a meter?

Step-by-Step Solution

The following steps will solve the problem using the Pythagorean theorem, which is given by the equation:

[ c^2 a^2 b^2 ]

In this scenario:

The length of the ramp is the hypotenuse (c) 3 meters (m) The distance from the base of the ramp to the truck (a) 2.82 meters (m) The height of the truck bed (b) is what we need to find

Let's substitute the known values into the equation and solve for b.

Step 1: Substituting Known Values

[ 3^2 2.82^2 b^2 ]

Calculating the squares:

[ 9 7.9524 b^2 ]

Step 2: Isolating b^2

[ b^2 9 - 7.9524 1.0476 ]

Now, we solve for b by taking the square root:

[ b sqrt{1.0476} approx 1.0236 ]

Step 3: Rounding to the Nearest Tenth

Rounding 1.0236 to the nearest tenth, we get:

[ b approx 1.0 ] meters (m)

Therefore, the height of the truck bed is approximately 1.0 meters (m).

Practical Application

The practical application of this problem is relevant in various real-world scenarios, such as:

Engineering and construction: Ensuring the correct dimensions for easy access to loading areas. Trucking and logistics: Calculating the optimal ramp length to navigate different heights of truck beds. Home improvement: Measuring the height of garage door openings or other raised surfaces.

Summary

In conclusion, the height of the truck bed, given the length of the ramp and the distance from the base of the ramp to the truck, is approximately 1.0 meters. This problem showcases the utility of the Pythagorean theorem in solving practical, real-world problems.
