Apply Area and Pythagorean Theorem to a prism

Click For Summary
SUMMARY

The discussion focuses on applying the Area formula for rectangles and the Pythagorean theorem to solve a problem involving a prism. The formula for the area of a rectangle is defined as A = L x W, while the Pythagorean theorem is expressed as A² + B² = C². Participants clarify the correct interpretation of area measurements, emphasizing that area should not be expressed in cubic feet. Additionally, the necessity of purchasing whole bundles, specifically 15, is confirmed, correcting any fractional bundle calculations.

PREREQUISITES
  • Understanding of basic geometry concepts, specifically area calculations.
  • Familiarity with the Pythagorean theorem and its application in geometric problems.
  • Knowledge of measurement units, particularly the distinction between square feet and cubic feet.
  • Ability to interpret and analyze visual representations of geometric problems.
NEXT STEPS
  • Study the application of the Pythagorean theorem in three-dimensional geometry.
  • Explore advanced area calculations for various geometric shapes beyond rectangles.
  • Learn about volume calculations for prisms and other three-dimensional figures.
  • Investigate measurement unit conversions and their relevance in geometry.
USEFUL FOR

Students studying geometry, educators teaching mathematical concepts, and anyone involved in practical applications of area and volume calculations.

Homework Equations


Formula for Area of a retangle : A = L x W
Pythagorean theorem: A2 + b2 = c2

The Attempt at a Solution



So I am pretty sure I did it correct but I just want to be 100% certain I will get this right, By the way its a picture cause I found it easier to just snip it then copy paste.

Thank you in advance for your help

Looks ok, as long as we disregard the fact that an area isn't measured in cubic feet and the "entire roof" is not 240 sqft. Calculation A, text D . :biggrin:
 
He will not need approximately 15; he will need to buy exactly 15. It would not be possible to buy 0.54 of a bundle.
 
@har your right just noticed that and thanks you

@fresh thanks you to :)
