The volume of railway car is 216 cubic meters
<em><u>Solution:</u></em>
Given that, Railway car is shaped like a rectangular prism with a length of 18 meters, a width of 3 meters and a height of 4 meters
To find: volume of railway car
<em><u>The volume of rectangular prism is given as:</u></em>

Where,
"l" is the length and "w" is the width and "h" is the height of prism
From given question,
length = 18 meters
width = 3 meters
height = 4 meters
Substituting the values, we get

Thus volume of railway car is 216 cubic meters
Answer:
Step-by-step explanation:
Inverse variation satisfies the form yx=k, if y=2 while x=-6 then
2(-6)=k, k=-12, then
yx=-12, when y=-3
-3x=-12
x=4
