Question 1116350
A rain gutter attached to the edge of a roof has the shape of a rectangular prism
 . It’s 18 feet long and 7 inches high it has a volume of 7,560 cubic inches .
 How wide is the gutter?
:
Change 18 ft to inches: 12 * 18 = 216
let w = the width of the gutter
the volume equation: 
 216 * 7 * w = 7560
 1512w = 7560
 w = 7560/1512
w = 5 inches is the width of the gutter
