anonymous 5 years ago Tammy is planting a garden that is 60ft.square feet. How many square inches is the garden?

1. anonymous

How many square inches are in a square foot?

2. anonymous

12?

3. anonymous

there are twelve inches along each edge, so how many little squares will you have in the big square?

4. anonymous

144

Correct. So if there are 144 square inches in each square foot, and you have 60 square feet, how many square inches will you have?

6. anonymous

144x60=8640?

7. anonymous

Also correct

You can check your answer using unit analyses: $60ft^2 = 60\times ft \times ft \times \frac{12in}{ft} \times \frac{12in}{ft} = 8640 \times in \times in = 8640 in^2$
