实验过程内容和结果怎么写

class cbox {
  constructor(length, width, height) {
    this.length = length;
    this.width = width;
    this.height = height;
  }
  // method
  volume() {
    return this.length * this.width * this.height;
  }
  // 按照长方体去计算的表面积
  surfaceArea() {
    return (
      this.length * this.width * 2 +
      this.length * this.height * 2 +
      this.width * this.height * 2
    );
  }
}

第二个自己来吧，尝试一下，不尝试永远学不会
