A rectangular prism has a length of 12 centimeters, a width of 6 centimeters, and a height of 9 centimeters. A cross section is
Klio2033 [76]

Answer:

<h2>The perimeter of the cross section is 30 centimeters.</h2>

Step-by-step explanation:

In this problem we have the intersection of a rectangular prism an a plane.

The dimensions of the rectangular plane are

l=12cm\\w=6cm\\h=9cm

Assuming the plane is cutting the prism horizontally, the cross section would have dimensions

w=6cm\\l=9cm

Because only the height would be cut.

So, the perimeter of the rectangle cross-section is

P_{cross}=2(l+w)=2(6+9)=2(15)=30cm

Therefore, the perimeter of the cross section is 30 centimeters.
