Given:
A right prism has height 7½ and triangular bases with sides of length 5, 12, and 13.
To find:
The total surface area of the prism.
Solution:
We have,
Height of prism = 7½ = 7.5
Sides of triangular base are 5, 12, 13. These sides of Pythagorean triplets because



So, the base of the prism is a right triangle.
Area of a triangle is



The area of the base is equal to the area of the top, i.e.,
sq units.
Perimeter of the base is


The curved surface area of the prism is



Now, the total area of the prism is



Therefore, the total surface area of the triangular prism is 285 square units.
Answer:
One of the possible dimensions of the full trailer could be 5 by 12 by 3.
Step-by-step explanation:
Volume = weight times height times length = 12 times 5 times 3 = 180.
Answer:
A box-and-whisker plot is shown above a number line that extends from 70 to 100 with 1 unit markings. The box extends from 79 to between 90 and 91 with a division at 89. There is also a point marked at 89. The whisker on the left extends from 75 to 79. The whisker on the right extends from between 90 and 91 to 93.
i hope this helps u and makes sense :))
Answer:
The range is (-3,∞)
Step-by-step explanation:
There is no specific range so it is infinite.
Hope I could help, if I was correct I hope you can consider marking me as brainliest! :D
