Question

For a contest, Dominique is stacking 3 super-long pens lengthwise on top of each other. Each pen is 2 feet long. If she succeeds, how many inches tall will her stack of pens be?

Answer 1

The stack of pens would be 72 inches tall. Each pen is two feet and there are three of them. Every foot has 12 inches. Multiply 12*2=24. Then multiply that by 3. so 24*3=72in
