It is known that the side length of a small cube is 0.01 meters. This small cube is placed into a large cube with a volume of 10 cubic meters, and several small cubes are needed
The first, second and third floors are all correct
The cube with a side length of 2 meters is made up of () small cubes of 1 cubic meter
The cube with a side length of 2 meters is made up of () small cubes of 1 cubic meter
To use () volume is 6 cubic centimeter small cube, can put together 90 cubic decimeter large cube
The cube with a side length of 2 meters is made up of (2) small cubes of 1 cubic meter
To use () volume is 6 cubic centimeter small cube, can put together 90 cubic decimeter large cube
The side length of a cube is 0.01 meters. How many cubes do you need to make a cube with a volume of 10 cubic meters?
One volume is 0.01 * 0.01 * 0.01 = 0.000001 cubic meter, the answer is 10 △ 0.000001 = 10000000 pieces = 1 * 107 (seven times of ten)
The side length of a small cube is 0.01. How many of these cubes can be used to make a cubic cube with a volume of 1 meter
0.01m=1cm,1m=100cm
1m^3=100cmX100cmX100cm=1000000cm^3
One million
A cuboid cistern is 12 meters long, 8 meters wide and 4 meters high. If the four walls and the ground are pasted with square tiles of 4 square decimeters, how many pieces do you need?
4 square decimeter = 0.04 square meter, [(12 × 8 + 12 × 4 + 8 × 4) × 2-12 × 8] / 0.04, = [(96 + 48 + 32) × 2-96] / 0.04, = [176 × 2-96] / 0.04, = 256 ／ 0.04, = 6400 (pieces); a: at least 6400 such tiles should be used
A swimming pool is 50 meters long, 25 meters wide and 4 meters high. Put ceramic tiles on its four walls and bottom. What is the area of the tile part
50X25+25x4x2+50x4x2=1850
Build a 20 meter long, 15 meter wide, 1.5 meter deep bath. If you use square tiles with an area of 5 square decimeters to paste the walls and floor, how many tiles do you need at least
Bottom area: 20 × 15 = 300 (M2)
Four wall area: (15 × 1.5 + 20 × 1.5) × 2 = 105 (M2)
Area to be paved: 300 + 105 = 405 (square meters) = 40500 (square decimeters)
Number of tiles required: 40500 ÷ (5 × 5) = 40500 × 25 = 1620
A: at least 1620 tiles are required
There is a triangular fountain, ready to paste tiles on the floor of the pool. If you use 200 mm × 200 mm tiles, you need to lay 25 tiles per square meter, at least how many tiles. You need to calculate the formula
If a 200 mm × 200 mm tile is 0.04 m2, then 1 m2 is 1 / 0.04 = 25. Calculate the area of triangle as s = a * H / 2, and then multiply the area by 25
How long is the square steel with a bottom area of 30x30mm2 to forge rectangular rough blanks with length of 300 mm, width of 200 mm and height of 60 mm?
300×200×60÷（30×30）
=3600000÷900
=4000（MM）
What is the weight of 8mm * 300mm * 300mm steel plate?
Volume already known? That is volume × 7.85g/cm & # 179; 0.8 * 30 * 30 * 7.85 = 5652g (or 5.652kg)
