A variable cost is a constant amount per unit produced or used. Therefore, the total amount of the variable cost will change proportionately with volume or activity. Generally, a product's direct materials are a variable cost. To illustrate, let's assume that a bakery uses one pound of flour at a cost of $0.70 per pound for every loaf of bread it produces.
Most sports fields are one hectare in size. The Apple Bowl in Kelowna for instance is a 400 m running track and the grassy area inside is 1.12 hectares. The international rugby field pictured above is very close to one hectare in size, it is actually 1.0008 hectares. A perfect square is 100 meters by 100 meters is a hectare. An acre is about 0.4047 hectare and one hectare contains about 2.47 acres.
The other measurement often used for surface area is the metric measure â hectares. A hectare is precisely 100 metres by 100 metres and is much larger than an acre. About 2.47 acres make up one hectare, so an acre is only about 40% of the size of a hectare.f you are trying to measure in approximate terms an acre of woodland you can pace it out as about 80 paces by 80 paces, though in woodlands people often take shorter paces so 70 yards may take more like 90 paces.
