Each vertical cross-section of the triangular prism shown below is an isosceles triangle. 8
What is the height, h, of the triangular prism?
Round your answer to the nearest tenth.

Step-by-step explanation:

use Pythagorean theorem:

a² + b² = c²

where a = h

           b = 8/2  = 4

           c = 5

plugin values into the formula:

h² + 4² = 5²

h² = 5² - 4²

x = √9

x = 3
