There are two ways of solving this.
You can convert the 17 feet to inches by multiply 17 by 12 ( 12 inches in 1 foot)
17 feet x 12 inches = 204 total inches.
The second way is to convert the 804 inches into feet by dividing 804 by 12.
804 inches / 12 inches = 67 feet.
In either way, you can see that 17 feet is not bigger than 804 inches.
