Question 106420

Construction: The amount of horizontal wood siding (in square feet) needed to cover a given wall area can be calculated from the formula.

let area of siding {{{(sq ft) = KX}}} total area to be covered (sq ft) be {{{A}}} 
where {{{K = 2.19}}}

if we need to cover a rectangular wall {{{60 ft}}} by {{{14 ft}}}, using {{{K=2.19}}}, then {{{A =2.19 (60ft)(14ft)}}}

{{{A = 1839.6ft^2}}}

let area of 1 rustic ship lapped drop siding  be {{{B}}}

then: {{{B = 1ft*6 ft = 6ft^2}}}


Now, we need to divide {{{A}}} by {{{B}}} in order to find out how many rustic ship lapped drop is needed.  Let number of it be {{{N}}}.

{{{N = 1839.6ft^2/6ft^2}}}  ……………here you eliminate {{{ft^2}}}

{{{N = 306.6}}}
