How many square centimeters are in an area of 8.50 inch^2
Paha777 [63]

Explanation:

Given parameters:

  Dimension = 8.5in²

we are to convert from in² to cm²

 in² = in x in

 cm² = cm x cm

   1 in = 2.54cm

Using dimensional analysis;

   8.5in² x \frac{2.54cm}{1in}  x \frac{2.54cm}{1in}

        =  54.84cm²

We solved this problem using dimensional analysis where we multiplied the unit with 1.
