The area in square feet.
Area conversions square the length factor, so the multiplier is 0.3048 squared, not 0.3048. Using the length factor by mistake OVERSTATES the area by a factor of about three — 500 sq ft comes out as 152.4 m² where the answer is 46.45 — so the slip shows up as an over-order rather than a shortage.

46.45 m²
1 sq ft = 0.3048² = 0.09290304 m² exactly. Area factors are the square of length factors — using 0.3048 instead of 0.0929 overstates area threefold.

Ordering metric materials against an imperial take-off starts here, and the single biggest error is using the length factor rather than its square. Area scales with the square of the linear dimension, so a square foot is 0.0929 square metres and not 0.3048 — a mistake that quietly multiplies an order by three and a quarter — 500 sq ft asks for 46.45 m², and the length factor answers 152.4. Beyond that, be careful with coverage rates: a paint quoted in square feet per gallon does not become square metres per litre by converting the area alone, since both the area and the volume change units. Convert your measured area, then read the product's own metric coverage from its tin rather than trying to convert the rate.
