【Question 2】
The ratio of the length, width, and height of a rectangular prism is $4: 3: 2$, and the total length of all edges is 72 centimeters. Try to find the volume of this rectangular prism.
【Analysis and Solution】
Geometry, Solid Geometry.
Since the ratio of the length, width, and height of the rectangular prism is $4: 3: 2$;
Let the length of this rectangular prism be $4 x$ cm, the width be $3 x$ cm, and the height be $2 x$ cm;
$$
4(4 x+3 x+2 x)=72 \text { ; }
$$

Solving for $x$ gives $x=2$;
The length of this rectangular prism is $4 \times 2=8$ cm, the width is $3 \times 2=6$ cm, and the height is $2 \times 2=4$ cm; the volume of this rectangular prism is $8 \times 6 \times 4=192$ cubic cm.
