A 48 cm long and 24 cm wide rectangular sheet iron is used to make a 6 cm deep uncovered cuboid container, and the thickness of welding joint and sheet iron is not considered How many welding methods can you find? How to weld the largest volume There are several welding methods, the length, width and height of each is OK

The height of the container is 6cm, and the height of the cuboid can be set as 6cm, so that the length and width of the cuboid can be set as a and B respectively. The known condition is the length and width of the rectangular sheet iron, and the area of the sheet iron can be calculated as 48 * 24 = 1152 square cm

How to weld a 10 cm deep cuboid uncovered iron box with a 80 cm long and 40 cm wide cuboid iron sheet

(80-10×2)×（40-10×2）×10
=60×20×10
=12000 (cm3)

With a piece of rectangular iron sheet 80 cm long and 40 cm wide, cut and put together a 10 cm deep uncovered cuboid, which can be welded. What is the volume of this container

Cuboid bottom length = 80-10x2 = 60cm width = 40-10x2 = 20cm bottom area = 60x20 = 1200 square cm
Volume = 1200x10 = 12000cc

There is a rectangular sheet of iron 80 cm in length and 40 cm in width. Please use it to make a 10 cm rectangular uncovered sheet iron box in Shenzhen market. The thickness of the sheet iron at the welding point
The larger the volume, the better. What's the volume of your tin box

80-20=60cm
40-20=20cm
60×20×10=12000cm³

A fraction is 13 / 27 (13 / 27), the numerator plus a certain number, the denominator minus a certain number, after the month is 5 / 3 (5 / 3), find a certain number

The expression of the meaning of the conversion topic
13 + X is a multiple of 5, so x is 2, 7, 12
27-x is a multiple of 3 and X is a multiple of 3
Then x is 12
The verification is consistent with the meaning of the question

How to express all kinds of negative emotions in English
Such as depression, depression, depression, etc., not limited to this

I am so upset / dissapointed / desperate / depressed / painful.

It is known that in △ ABC, ∠ ACB = 90 ° AC = BC, the straight line Mn passes through point C, and ad ⊥ Mn is in D, be ⊥ Mn is in E

It is proved that: ① ∵ - ACB = 90 °, be ⊥ CE, ad ⊥ CE, ∵ - BEC = - ACB = - ADC = 90 °, ∵ - ACE + - BCE = 90 °, ∵ BCE + - CBE = 90 °, ∵ ACD = - CBE, in △ ADC and △ CEB, ≌ - ADC = - BEC ≌ ACD = - cbeac = BC, ≌ - ADC ≌ - CEB (AAS)
