Answer
39,304 times as large
Work Step by Step
Since the actual length of each side is 34 times as large, the volume is $34^3$ as large.
$34^3$=39,304
Area is the product of width, length and height.
The area of the model is:
2×9×4=72 sq in
If the scale is 1:34, each side of the actual truck is 34 times as large as the model. The area of the actual truck is:
2(34)×9(34)×4(34)=68×306×136=2,829,888 sq in
Divide the actual area by the area of the model to find how many times greater
2,829,888÷72=39,304
