You can buy cardboard with the dimensions 1m x 1m at various places such as office supply stores, craft stores, packaging supply stores, and online retailers. Look for specialty stores that sell large sheets of cardboard or contact local packaging companies to inquire about purchasing cardboard sheets in the specific size you need. Additionally, you can check with local hardware stores or home improvement centers as they may carry large sheets of cardboard for various purposes. **

The diameter of a 1m circle is also 1m. The diameter is the distance across the circle passing through the center, so in the case of a 1m circle, the diameter is also 1m. This means that if you were to measure from one side of the circle, through the center, to the other side, the distance would be 1m. **

The number of pots that can fit on 1m² depends on the size of the pots. For example, if we consider small pots with a diameter of 10cm, approximately 100 pots can fit on 1m². However, if we use larger pots with a diameter of 20cm, only around 25 pots may fit on 1m². Therefore, the number of pots that can fit on 1m² varies based on the size of the pots being used. **

Good 1m saddle girths are those that are made of high-quality materials such as leather or synthetic materials like neoprene. They should have strong, durable buckles and hardware to ensure they can withstand the rigors of riding. Additionally, a good 1m saddle girth should be designed to distribute pressure evenly and prevent chafing or rubbing on the horse's skin. Look for girths with features such as elastic inserts or contoured shapes to provide a comfortable fit for the horse. **

One way to measure an area of 1m by 1m without a ruler or measuring tape is to use a standard piece of paper. A standard piece of paper is 21cm by 29.7cm, so you can use it to measure out the 1m by 1m area by aligning the edges of the paper and counting how many times it fits within the area. Another method is to use your own body as a reference. For example, you can lay down on the ground and measure out the 1m by 1m area using the length of your body as a guide. **

The amount of oxygen contained in 1m³ can vary depending on the conditions such as temperature and pressure. However, under standard conditions (0°C and 1 atmosphere of pressure), 1m³ of air would contain approximately 21% oxygen, which is equivalent to 0.21m³ of oxygen. Therefore, the volume of oxygen in 1m³ of air would be approximately 0.21m³. **

Both being 1m short and 2m tall have their own advantages and disadvantages. Being 1m short may make it easier to find clothes that fit and to navigate through small spaces, while being 2m tall may provide a better view in crowds and can be advantageous in certain sports. Ultimately, the ideal height is subjective and depends on personal preferences and individual circumstances. **

The concept of "better" is subjective and depends on personal preferences and needs. Being 1m small may have advantages such as being more agile and fitting into smaller spaces, while being 2m tall may have benefits like better reach and visibility. Ultimately, it is important to embrace and appreciate our unique characteristics, regardless of our height. **
