Formula (LaTeX) + variables + units

This section shows the formulas used by the calculator engine, plus variable definitions and units.

Formula (extracted LaTeX)

\[', right: '\\]

', right: '\

Formula (extracted LaTeX)

\[A_{wall} = \text{Wall Perimeter} \times \text{Room Height}\]

A_{wall} = \text{Wall Perimeter} \times \text{Room Height}

Formula (extracted LaTeX)

\[A_{gross} = A_{wall} + A_{ceiling}\]

A_{gross} = A_{wall} + A_{ceiling}

Formula (extracted LaTeX)

\[A_{net} = \max(0, A_{gross} - A_{openings})\]

A_{net} = \max(0, A_{gross} - A_{openings})

Formula (extracted LaTeX)

\[A_{total} = A_{net} \times (1 + \frac{\text{Wastage \%}}{100})\]

A_{total} = A_{net} \times (1 + \frac{\text{Wastage \%}}{100})

Formula (extracted LaTeX)

\[N_{sheets} = \lceil \frac{A_{total}}{A_{sheet}} \rceil\]

N_{sheets} = \lceil \frac{A_{total}}{A_{sheet}} \rceil
