It is welded with a 110cm long angle iron

This should be the third question on page P16 of the Huanggang Xiaozhuangyuan Teaching Edition of Mathematics in the fifth grade of primary school!

Weld a rectangular frame with a 110 cm long angle iron, the length is twice the width, and the width is twice the height, find what is the length, width and height of this cuboid?

Let its height be x, then its width will be and its length will be 2

According to the title: x+

This cuboid is 15 centimeters long, centimeters wide, and 5 centimeters high.

Solution: If the height is x, then the width is and the length is 3x. x+

The original question is: the length is 2 times the height, the width is the height of the high, find the ...... of this rectangle

Did you make a mistake, or did you make a mistake in the book?

Height: cm.

Length: 5 3 = 15 cm.

Width: 5 cm.

The length, width, and height of the cuboid are 4 each, and the sum of the length, width, and height of one of them: 110 4 = cm.

From "length is 2 times the width, width is a multiple of the height", we know: length: width: height =: 1 and then proportional distribution of the idea of answering: 3+

Height: cm. Length: 5 3 = 15 cm.

Width: 5 cm.

Let its height be x, then its width will be and its length will be 2

The x+ cuboid is 15 centimeters long, centimeters wide, and 5 centimeters high.

Choose to get drunk and remember the red dust.

She's right.

Summary. To calculate the number of wires used in a fillet weld, you need to know the amount of wire required per meter as well as the length of the weld. Assuming the welding length is 100 meters and the welding angle is 14 degrees, the welding is carried out using a wire with a diameter of millimeters.

Due to the complexity of the shape of the weld fillet seam, it cannot simply be calculated by multiplying the length by the amount of wire required per meter. Only estimates can be given here. Normally, the welding efficiency of the welded corner seam is low, and it is difficult to achieve 100% welding effect.

When calculating, it is generally calculated according to the welding efficiency of 60%. That is, the average width of the weld with a "V" shape per meter is 2 mm, the depth is millimeters, and the amount of welding wire required per meter is about kilograms. Therefore, a 100-meter-long welding corner seam requires about kilograms of wire, which is about 12 reels of 1 kilogram of wire or 24 reels of kilogram of wire.

Fillet weld, 14,100 meters long approximate how many coil wires are used.

That is, the average width of the weld in the shape of "V" per meter is 2 mm, the depth is mm, and the amount of wire required per meter is about kilogram changna. Therefore, a 100-meter-long welding corner seam requires about kilograms of wire, which is about 12 reels of 1 kilogram of wire or 24 reels of kilogram of wire. This value is for reference only, the actual amount of welding wire used may vary, and it needs to be adjusted according to the actual situation.

Can you add, I don't quite understand it.

If two iron bars with a length of 100 cm are welded into one, and the joint part is 10 cm long, how many cm is the length of the welded iron bar?

The calculation process is as follows: 100 2-10 = 200-10 = 190 (cm) A: The length of the iron bar after welding is 190 cm.

25x2 = 50 (mm) = 5 (cm).

20x3-5=55 (cm).

A: The length of the wire is 55 cm.

2 meters = 200 centimeters.

70 cm (the length of the iron bar welded).

Weld two 10 cm wires into one, the welding section is 2 cm long, and the welded wire is 6 cm long.

The calculation process is as follows:

I know it according to the title.

The length of the welding section is 2 cm, indicating that the overlapping part of the two wires is 2 cm.

Wire length after welding:

6 (cm).

Weld two 25cm iron bars with a 5cm welding head, and 45 cm long after welding.

The calculation process is as follows:

Weld two iron bars into one, the joint part is 10 cm long, and the welded iron bar is 190 cm long, the original one of the iron bars is 80 cm long, and the other is how many cm long.

Hello, the solution process is as follows: 190-10-80 = 100 (cm) so the other one is 100 cm long.

Hello, 3 iron sheets 20 cm long, welded into one, the welding head part is 25 mm long, and the total length of the wire after welding isCentimeter.
