Problem

Jackson's paintbrush makes a narrow strip with a width of 6.5 millimeters. Jackson has enough paint to make a strip 25 meters long. How many square centimeters of paper could Jackson cover with paint?

$\textbf{(A) }162,500\qquad\textbf{(B) }162.5\qquad\textbf{(C) }1,625\qquad\textbf{(D) }1,625,000\qquad\textbf{(E) }16,250$

Solution

$6.5$ mm = $0.65$ cm

$25$ m = $2500$ cm

$0.65\times2500=\boxed{\textbf{(B) }1,625}.$
