How long is 3 4 meters, 2 meters wide, 2 2 meters high, 30 cm thick, and what is the gray surface?

Solution: If this is a building, it means that the wall thickness is 30 centimeters, the length of the outer wall is meters, the width of the meter, the height of the meter, and what is the area of the wall covered with ash inside? Because you don't have windows and doors, then the floor is not covered with ash, and the four walls and the roof need to be dusted.

The area of the roof + the area of the front and rear walls + the area of the left and right walls.

Length 2 thick) x (width 2 thick) + (length 2 thick) x (height 2 thick) + (width 2 thick) x (height 2 thick).

Square metre. A: The plastered area of the wall that needs to be plastered is the square meter to remove the floor.

It is 30 centimeters long, wide, and high, so if you have a face, its area is generally about 24 square centimeters.

If there is a covered cube:

Length * width on both sides.

Both sides are long * high.

Height * width on both sides.

2 (sq.m.)

In the case of a cube without a lid:

One side is long * wide.

Both sides are long * high.

Height * width on both sides.

Square metre.

Hello dear, glad to answer for you. How many square meters of ash do you need for meter length, width and thickness 10 If this cement floor is to make 10 cm thick standards, then one square can probably use square concrete. Just such a square of concrete requires about 2,400 kilograms of material.

You need about 240 kilograms of concrete for a square 10 centimeters thick. Of course, concrete is also divided into many models of Sun Kai and, different models are used in different places, roads are built with special concrete, then the wall and buildings are also built by different concrete, general architectural designers will have a clear mark, most of the concrete used on the building model is C25.

Summary. Cubic meters, pro, glad to ask for you.

The length is meters, the width is meters, the height is meters, and the thickness is meters, etc.

Cubic meters, pro, glad to ask for you.

Dear, it's cubic meters, I hope it can help you.

Calculate the cube formula: length, width, height.

Summary. Hello, dear. It is 30 meters long and 20 meters high, and has 1,920 square meters of soil.

Hello, dear. It is 30 meters long and 20 meters high, and has 1,920 square meters of soil.

Calculation process: volume = bottom area height = length width height = 30 20 cubic meters.

So it is 30 meters long and 20 meters high, and there are 1,920 square meters of soil.

According to the volume formula, we know that 1 meter 100cm, volume = length width height = 21 * cubic meters? So cubic meters are needed.

30 centimeters = meters.

cubic meters) A: Square ash is required.

Hello, I am glad to answer for you, 2 meters 4 wide 2 meters 4 high 2 thousand meters long 30 centimeters thick to noisy beam cubic meters of concrete. The volume of the soil section is: 2000m = cubic meters, therefore, the volume of concrete required is cubic meters.

Dear, I hope it can help you and wish you a happy life! 

Summary. Based on the given dimensional information, calculate the volume of sand required to fill this space. First calculate the volume of this space:

Length, width, height=5 meters, 3 meters, meters=33 cubic meters. The thickness is then converted to meters, i.e. 20 centimeters = meters, and the volume of sand in each layer is calculated: 5 meters 3 meters meters = 3 cubic meters.

Finally, divide the volume of the entire space by the volume of sand in each layer to get the required number of sand layers: 33 cubic meters 3 cubic meters = 11 layers. Therefore, it takes 11 layers of sand to fill this space.

It is 5 meters long and 3 meters wide, high and 20 centimeters thick, and how much sand is needed.

Based on the given dimensional information, calculate the volume of sand required to fill this space. First, calculate the volume of this space: length, width, height = 5 meters, 3 meters, meters = 33 cubic meters.

Then the thickness is converted to meters, i.e. 20 centimeters = meters, and the volume of sand in each layer is calculated: 5 meters 3 meters meters = 3 cubic meters. Finally, divide the volume of the entire space by the volume of sand in each layer to get the required number of sand layers:

33 cubic meters 3 cubic meters = 11 floors. Therefore, it takes 11 layers of lead sand to fill this space.

I'm sorry I don't understand, but can you elaborate on that?

The volume of sand is calculated according to the given dimensional information: length, width, height = 5 m, 3 m, m = 33 cubic meters. Convert the thickness to Brother Rock Meter:

20 cm = m. Calculate the dust beat volume of sand sail in each state: 5 meters 3 meters meters = 3 cubic meters.

The volume of the entire space is divided by the volume of each layer of sand to obtain the number of sand layers: 33 cubic meters 3 cubic meters = 11 layers. So it takes 11 layers of sand to fill this space.

Meters long, 43 high, 30 wide is 2838 square, the calculation formula is as follows.
