To find the height of the box, you will use the formula for finding volume of a prism and solve for the height.

V = Bh, where B is the area of the base

439.2 = 1/2 x 6.9 x 18 x h
439.2 = 62.1h
h = 7.07

The height of the triangular prism is approximately 7.07 inches.

Answer:

Step-by-step explanation:

The sum of measures of angles in triangle is 180°

so:

180° - 90° - 45° = 45°

two angles angles of the same measure, that means: x = 7

so:

$7^2+7^2=y^2\\\\y^2=7^2\cdot2\\\\y=\sqrt{7^2\cdot2}\\\\\bold{y=7\sqrt2}$
