Roofing materials calculations.?

Hi I need to find out how many planks of plywood I should buy for my flat roof.

The length of my roof is approx. 56 ft and the width is 19 ft.
I calculated the area to be about 1064 ft.

If the plywood is 4×8, how much plywood will I need to cover the roof.

(19 ft)(56 ft) = 1,064 ft^2
(4 ft)(8 ft) = 32 ft^2
(1,064 gt^2) / (32 ft^2) = 33.25 sheets ==> 34 sheets
if and only if scrap is worked into the roof pattern.
