A cube paper box can just put a cylinder with a volume of 6280 cubic centimeters. How many cubic centimeters is the volume of this paper box
The volume ratio of the cylinder to the volume of the cube is 157:200
Therefore, the volume of cube carton is 6280 △ 157 × 200 = 8000 (cubic centimeter)
In a cube box, you can put a 282.6 cubic centimeter cylinder roll paper
Easy! If the height is the same, there is only the problem of area? The area of a circle is a quarter of the area of a square of the same length
In other words, 282.6 * 4 / 3.14 = 360
A cylinder is just put into a cube carton. It takes 150 square meters of paper to make the carton. The volume of the cylinder is []
Area of one surface of cube = 150 △ 6 = 25 (M2)
Because: 25 = 5 × 5
So: cube edge length = 5m
It is concluded that the diameter of the bottom of the cylinder = the height of the cylinder = the length of the cube = 5m
Area of column bottom = 3.14 × (5 △ 2) & # 178; = 19.625 (M2)
Cylinder volume = 19.625 × 5 = 98.125 (M3)
In a cube box, a cylinder roll with volume of 282.6 cubic centimeter can be put into it. The volume of the cube can be calculated by equation
The side length of a cube is equal to the diameter of the top surface of a cylinder and the length of its height
Let l be the side length of a cube,
Then the diameter of the secondary cylinder is l and the height is L,
Cylinder volume = bottom area x height = square of π × (L / 2) × L = π (L / 4) × L = π / 4 x cube of L = 282.6
Cube of L = 282.6 / (π / 4)
So cube volume = L ^ 3 = 282.6 / (π / 4) = 360 cubic centimeter
Use square pieces of paper to make a cube box. The side length of the paper is 6cm. At least how long does it take to glue the box? On the surface of the box
What is the area of the trademark?
12x6=72(cm)
A: it takes 72 cm of tape to stick the box
If the bottom of the box is square, the height of the box is the smallest
If the height of a cuboid carton is increased by 2cm, it will become a cube. At this time, the surface area is increased by 56cm, and the volume of the original cuboid carton is calculated
Circumference of the bottom of the cuboid = 56 △ 2 = 28 cm
Side length of cuboid bottom (square) = 28 △ 4 = 7 cm
The height of the original cuboid is 7-2 = 5cm
The original cuboid volume = 7 × 7 × 5 = 245 cubic centimeters
A cube box can fit a cylinder with a volume of 628 cubic centimeters. Please find out the volume of the box?
Is there a formula
(1) Volume of the cylinder: v = π × R × R × H = π × (D / 2) × (D / 2) × H = (π × / 4) × D × D × h; R is the radius of the bottom of the cylinder, D is the diameter of the cylinder, H is the height of the cylinder, known as v = 628 cubic centimeter, 628 × 4 = π × D × D × h, get: 800 = D × D × h, there should be a cube box to hold such a
The straight line y = 2 / 3x - 2 intersects the X axis and Y axis at two points a and B respectively, and O is the origin
Can we draw a straight line through the vertex of the triangle AOB, and divide the triangle AOB into two parts with equal area? If so, how many can we draw? Write out the corresponding functional relationship of such a straight line
It is known that the intersection points of the straight line and X, Y axes are (3,0), (0, - 2) respectively
Knowing the coordinates of the three vertices, it is easy to find out the coordinates of the middle points of the three sides (3 / 2,0), (0, - 1), (3 / 2, - 1), and the lines where the middle lines of the three sides are located are the three lines that divide the area equally
The line y = 2 / 3x-2 intersects the X and Y axes at two points a and B respectively, and O is the origin
1. Can we draw a straight line through the vertex of Δ AOB? 2. If we can, how many can we draw? 3. Write the corresponding functional formula of such a straight line "write the process of calculation"
The process of a straight line passing through points o and ab
A straight line passing through O and E (3 / 2, - 1) of a (3,0) and B (0, - 2) can divide the area of triangle into two equal parts. In this case, the function expression of the straight line is y = - (2 / 3) X
