Please answer a 6th grade math problem in detail

Let the unit weight be a, it is known that B has 3a more goods than A, and when the goods of A and B are equal, the goods in each warehouse should be because the total weight is 2a+5a), so the goods shipped by B are = tons.

So a = = t.

So A original cargo = * 2 = tons.

B: Original cargo = * 5 = 68 tons.

If warehouse A originally had x tons, then warehouse B had 5 2x

x+x=So, warehouse A has tons and warehouse B has 36 tons.

of the total volume of goods.

The total amount of goods can be found i.e.

A occupies B.

portions) tons).

Tons) Tons) A: Tons in warehouse A, 68 tons in warehouse B.

The correct quotient is 23, and the remainder is 11. . .

Based on the wrong divisor and the wrong quotient and remainder, the correct dividend can be calculated (because the dividend has not changed) is 23x32+11=747

Divide 747 by the correct divisor of 32 to get the answer.

The original number is 23*32+11 =747

The correct quotient is 747 32 = 23 ...11

The quotient is 23 and the remainder is 11

First calculate what the dividend is, you can use the wrong 23 to calculate, that is, 23 * 32 + 11 = 747, and then divide the dividend by the divisor, that is: 747 32 = 23 and the remainder of 11

Down payment 400,000 * 30% = 120,000 (yuan) loan 400,000-120,000 = 280,000 (yuan) commercial loan 280,000*

Housing provident fund loan 280,000*).

Save 583,400-513,400 = 70,000 (yuan) Answer: You can choose a provident fund loan, which is 70,000 yuan less than a commercial loan.

Ahh

Use the centimeter side to make the bottom circumference, the diameter is centimeter, and the height is centimeter;

Use the centimeter side as the base circumference, the diameter is = 6 cm, and the height is the centimeter.

In both cases.

There are two kinds of ah, horizontally and vertically.

Width: Height 6cm in diameter

Vertical: height 8cm in diameter

1. If the length is the bottom roll, the height is and the bottom diameter is = 8 cm

2. If the width is the bottom roll, the height is and the bottom diameter is = 6 cm

There are two kinds, one horizontal and one vertical.

Horizontal: Height 6cm in diameter

Vertical: height 8 cm in diameter

Hehe..

The area of the cuboid, the front and back sides, the left and right sides, and the upper and lower sides, respectively:

60 3 = 20 square centimeters.

60 4 = 15 square centimeters.

60 5 = 12 square centimeters.

The original surface area was:

20+15+12) 2=94 square centimeters.

The length of the order is a cubic centimeter, the width is b cubic centimeter, and the height is h cubic centimeter.

3ah=4bh=5ab=60

3ah）*（4bh）*（5ab）=60^3=216000∴（abh）^2=3600

abh=60

Therefore, the volume is 60 cubic centimeters.

Let the length be x, the width be y, and the height be z

Untie. (x+3)yz-xyz=60 yz(x+3-x)=60 yz=20

x(y+4)z-xyz=60 xz(y+4-y)=60 xz=15xy(z+5)-xyz=60 xy(z+5-z)=60 xy=12 area = (length x height + length x width + width x height) x2 = (xz + xy + yz) x2 = (15 + 12 + 20) x2
