Use iron wire to weld a cuboid frame of 15 cm long, 10 cm wide and 5 cm high. How many cm of iron wire is required at least Be accurate and quick

Use iron wire to weld a cuboid frame of 15 cm long, 10 cm wide and 5 cm high. How many cm of iron wire is required at least Be accurate and quick

15*4+10*4+5*4=120

How many centimeters of wire is needed to weld a 12 cm long, 10 cm wide and 5 cm high rectangular frame with wire?

12×4+10×4+5×4=108
The length, width and height need 4 pieces respectively

A piece of iron wire is 24 cm long. Weld it into a cuboid frame which is 1 cm wide and 1 cm high. How long is the cuboid frame?

The answer is: 4cm

A 3M long steel pipe is sawed into 5 sections, each section is full length (), each section is long (), each section is 6m long ()

1/5 0.6m 1/10

A steel pipe is 5 meters long. Now it is sawed into several equal length segments. A total of 6 times have been sawed. How many parts of the steel pipe is each segment? The average length of one segment has been sawed
What fraction of the total time is time?

A steel pipe is 5 meters long. Now it has been sawed into several equal length segments for six times. Each segment is one seventh of the length of the steel pipe, and the average time of sawing a segment is one sixth of the total time

The 5-meter-long steel pipe is sawed into 7 sections, each section is long______ The length of each segment is 1______ ．

The number of meters of each section: 5 △ 7 = 57 (meters), the percentage of each section in the total length: 1 △ 7 = 17. Answer: each section is 57 meters long, and each section accounts for 17. So the answer is: 57, 17

Divide the 3-meter-long steel pipe into 4 sections, each section is () () of the steel pipe, and each section is long______ Rice

1 △ 4 = 143 △ 4 = 34 (m) or 3 × 14 = 34 (m)

The 3M long wire is divided into 5 sections, each section is a few tenths of a meter long, and each section is a few tenths of a 3M long wire

The 3M long wire is divided into 5 sections, each section is 3 / 5 of the length, and each section is 1 / 5 of the 3M length

Divide a 4 / 3 m long iron wire into 6 sections on average. How long is each section of iron wire? What is the proportion of each section of iron wire to the total length?

Three quarters divided by 6 = one eighth. One eighth divided by one fourth equals one sixth

A 3M long iron wire is divided into 5 sections, each section is a fraction of the length of the wire, and the length of each section is () m, which is equivalent to ()% of 1m

A 3M long iron wire is divided into five sections, each section is one fifth of the length of the wire, and the length of each section is (3 / 5) m, which is equivalent to (60)% of 1 meter
