Find the height in inches of a wall that is 6 inches less than 12 feet tall.
Gre4nikov [31]

Answer: I believe its 138 inches, if 'wrong i'm sowwy.

Step-by-step explanation: It sates to find the height of the was 6 inches less than 12 feet tall, this means were subtracting 6 (less than) into 12 feet. We cant do that until we convert inches into feet. we know that 12 inches is equal to 1 foot.

Easier way to do this is to .. multiply 12 by 12 which is = 144

12 inch = 1 ft

24 inch = 2 ft  

SO, 144 - 6 = 138

To convert this into feet we divide 12 into 138 which is 11.5 feet.
