用Golang编写一个程序来绘制一个2 X 3 X 6尺寸的长方体。长方体可以以图形方式表示，也可以以ASCII艺术形式表示，具体取决于语言功能。为了满足长方体的标准，必须有三个面是可见的。

package main
 
import "fmt"
 
func cuboidDraw(drawX, drawY, drawZ int) {
    fmt.Printf("Cuboid %d %d %d:\n", drawX, drawY, drawZ)
    cubeLine(drawY+1, drawX, 0, "+-")
    for i := 1; i <= drawY; i++ {
        cubeLine(drawY-i+1, drawX, i-1, "/ |")
    }
	cubeLine(0, drawX, drawY, "+-|")
    for i := 4*drawZ - drawY - 2; i > 0; i-- {
        cubeLine(0, drawX, drawY, "| |")
    }
    cubeLine(0, drawX, drawY, "| +")
    for i := 1; i <= drawY; i++ {
        cubeLine(0, drawX, drawY-i, "| /")
    }
    cubeLine(0, drawX, 0, "+-\n")
}
 
func cubeLine(n, drawX, drawY int, cubeDraw string) {
    fmt.Printf("%*s", n+1, cubeDraw[:1])
    for d := 9*drawX - 1; d > 0; d-- {
        fmt.Print(cubeDraw[1:2])
    }
    fmt.Print(cubeDraw[:1])		
    fmt.Printf("%*s\n", drawY+1, cubeDraw[2:])
}
 
func main() {
	fmt.Println("Enter 3 dimensions of Cuboid : ")
    var l,b,h int
    fmt.Scanln(&l)
	fmt.Scanln(&b)
	fmt.Scanln(&h)
	cuboidDraw(l,b,h)
}

输出：
