4.9 sq ft = __ sq in?

OpenStudy (anonymous):

58.8 sq in

OpenStudy (jamesj):

There are 12 inches in a foot. Draw a diagram of one square foot and look at the matrix of 12 x 12 inches. Then you can see that 1 sq.foot = 12^2 sq.inches = 144 sq.inches Hence ...

mad scientists101 how did u work that problem

OpenStudy (anonymous):

Take 4.9 and multiply it by 12.

OpenStudy (anonymous):

the sq part doesnt count

OpenStudy (anonymous):

4.9ft*(12inches/1ft)=58.8in

OpenStudy (anonymous):

You have sq on both sides

OpenStudy (jamesj):

What madscientist wrote down is wrong. It's NOT just times 12. It's times 12 squared. Draw the diagram I suggest and you'll see why.

OpenStudy (anonymous):

OpenStudy (anonymous):
