Convert kg to cubic meters how many kg to one cubic meter

SOURCE: 1. convert 10,000 Square meters

1. You cannot convert square meters (m²) to meters (m). The first unit measures an area, the second a length. You might as well ask, "what is the weight of two hours".
   
2. There is no single answer without further constraints given. Even assuming a box-shaped room, it might be, for example 1ft x 1ft x 300,000ft or 100ft x 100ft x 30ft. Infinite more combinations are possible.
3. My pleasure ;-)
   

SOURCE: hi i need to calclate

the 60 by 30 meters is easy. that is 1,800 meters squared. Since 1 inch is equal to 0.0254 meters, 12 inches equals 0.3048 meters. multiply that by the 1,800 you already have and you get 548.64 meters cubed

SOURCE: how to convert cubic meters

That is something that cannot be done (cubic to square). You can convert cubic meters to cubic feet or square meters to square feet as follows:

Multiply cubic meters by 35.3146 to get cubic feet

Multiply square meters by 10.7639 to get square feet

SOURCE: hi i need to know how to convert 80 sq ft to cubic

You don't. Square feet is a measure of area while cubic meters is a measure of volume.

Consider a room 8 ft by 10 ft. The floor area is 80 square ft. What's the volume of the room in cubic feet (let's not worry about converting to meters yet). Well, that depends on the height of the ceiling, doesn't it? If the ceiling is 8 ft high then the volume is 640 cubic feet. If the ceiling is 12 ft high then the volume is 960 cubic feet. Without that third dimension, you can't calculate the volume.

SOURCE: all i need to know is how do u convert 9ft lenght

Here is the basic knowledge to help find your answer
1inch=2.54 cm
1cm=0.01 m
1foot=12 inches=12*2.54 cm=30.48 cm=0.3048 m
Volume of timber =2*2*9 *(0.3048)^3 m^3=1.019 steres
