A rotation of 180 degrees preserves a figure’s orientation
kotegsom [21]
This is false. If you rotate a figure 180 degrees, then the figure will not have the same orientation, it will be upside down and in another quadrant.

a clothing truck is shaped like a rectangular prism.The volume of the truck is 15 ft. The area of the base of the container is 6
Olin [163]

Answer:

2.5 ft

Step-by-step explanation:

A rectangular prism's volume is given by it's base area multiplied by it's height:

V = A_b * h

In this problem, we are given the volume and the base area, so we need to solve for h:

h = \frac{V}{A_b}

h = \frac{15}{6} = 2.5

The units are feet, so the answer is 2.5 ft.
