The cuboid is 12 cm long and 8 cm high. The sum of the areas of the two sides of the shadow is 200 square cm. What is the area of the cuboid?

The cuboid is 12 cm long and 8 cm high. The sum of the areas of the two sides of the shadow is 200 square cm. What is the area of the cuboid?

200-12x8 divided by 8 = 13
(13 is wide)
12x13x8
=156x8
=1248 (CC)

The length of the cuboid is 12 cm, and the area of the two sides of the 8 cm high shadow part is 200 square cm. How many cubic centimeters is the area of this cuboid
(left and bottom)

The width of the cuboid is 10 cm
The surface area is 592 square centimeters
The volume is 960 cubic centimeters

The solution of the system of binary linear equations x + y = 5kx − y = 9K is the solution of binary linear equations 2x + 3Y = 6, then the value of K is ()
A. k＝−34B. k＝34C. k＝43D. k＝−43

If x + y = 5kx − y = 9K, then x = 7ky = − 2K, and then substitute into the equation 2x + 3Y = 6, then 14k-6k = 6, then k = 34, so choose B

There is a difference of 10 tons between the two warehouses. If Party A delivers 20% of the goods, and Party B delivers one fourth of the goods, the inventory quantity of the two warehouses will be the same. How many tons of goods did the two warehouses have

B is a's (1-20%) / (1 + 1 / 4) = 4 / 5 / 5 / 4 = 16 / 25, a's original 10 (1-16 / 25) = 10 / 9 / 25 = 250 / 9 tons, B's 250 / 9-10 = 160 / 9 tons, click [evaluation] in the upper right corner, and then you can choose [satisfied, the problem has been solved perfectly]

Like the two vertical forms on the left, you can write several vertical forms 17 62 + 71 + 26 with the result of 88

35+53=88
44+44=88
There are only two

Buy fruit
Buy 100 of three kinds of fruits with 50 yuan. The name and price are as follows:
Watermelon - $5 each
Apple - $1 each
Plums - 1 jiao each
Excuse me: how much did you buy for each fruit?

Suppose x watermelon, y apple and Z plum;
x+y+z=100；
5x

If S3 = 12 and 2A1. A2.1 + a3 are equal ratio sequence, the general formula of {an} can be obtained

s3=3(a1+a3)/2=3a2=12 a2=4 (a2)^2=2a1*(1+a3)=2(a2-d)*(1+a2+d)
We can get d = 3 A1 = a2-3 = 1 an = 3n-2

Simple calculation of 36.72 / 2.4 + 100

36.72/2.4+100
=36/2.4+0.72/2.4+100
=15+0.3+100
=115.3

a. B, C, D are rational numbers. Now we define a new operation... │ a, B │ C, d = ad BC. Then when │ 2x 4 │ 1-x5 = 14, we can find the value of X

The question you wrote = 14 is 2 times 4? 1 minus X5

The ratio of 0.2, 5, 4 / 5, 1 and 1 / 4 is ()
I really don't know how to make these four numbers into different proportions!
The first answer is adopted immediately.

What is the proportion of the composition
4:0.2:5 = 1 and 1:5
