Volume: 8 * 6 * 4 = 192 cubic meters.
What about the unit price of lacquer?
Tile area: 8x1x2 + 6x1x2 = 28 square meters of painted area: 8x3x2 + 6x3x2 + 8x6 = 132 square meters - 2x2 = 128 square meters.
Brush twice: 128x2 = 256 square meters.
To paint: 256 4 = 64 kg.
A total of 64x(100 25)=256 yuan to buy paint.

Solution: (1) The volume of the warehouse: 8 6 4 = 192 (cubic meters) (2) The ground area: 8 6 = 48 (square meters).
Paint required: kg).
3) The area of the tile: length 1 2 + width 1 2-2 1, that is: 8 1 2 + 6 1 2 - 2 1 = 16 + 12-2
26 (sqm).
130 (sqm).
130 4 = kilograms).
100 (Note: Brush 2 twice here, and if you don't say you don't sell zero, buy a bucket】=100
260 (yuan) [If: don't open and sell, then buy 3 barrels for 300 yuan].
-
1)8*6*4=192
2) 8*6*kg.
I don't know the unit price, so I can't calculate how much yuan is needed, I only know that I need kilograms, and if I know the unit price, I can multiply it by the unit price.
The area of the tiles is 26 square meters.
4) The area that needs to be brushed ((8 + 6) * 2-2) * (4-1) + 2 * (4-2) + 8 * 6 = 130 square meters.
The number of kilograms of paint required is 130 4=
Number of barrels needed.
Because you need to brush it twice.
So you need a bucket to get a total of yuan.
But usually, problems like this are taken into 1, so it takes 3 barrels, a total of 3 * 100 = 300 yuan.

8*5*2+6*3*2+8*6)-2*2=160 (square meters) 160 divided by 4 equals 40 (kilograms).
100 divided by 25 equals 4 (yuan per kilogram).
40*4=160 (yuan).
160*2=320 (yuan).
Answer: It costs a total of 320 yuan to buy paint.

Area = 8 6 + 1 (8 + 6) 2-2 2 = 72 square meters.
Paint = 72 4 25 2 100 = 144 yuan.

The perimeter of the floor is multiplied by the height of the tile to be tiled by 1 metre, minus the area occupied by the door opening.

A cuboid warehouse is 8 meters long, 6 meters wide and 2 meters high, and the warehouse is equipped with a door, which is 1 meter wide and 2 meters high. Now we need to put tiles on the four walls of the warehouse less than 1 meter above the ground, what is the area of the tiled part?
Don't think about the door yet. In this case, the tiles are on four walls. The area that needs to be tiled is 2 (8 1 + 6 1) = 28 square meters because the wall is dug into the door, deducting 1 1 = 1 square meters. Therefore, the area that needs to be tiled is 28-1=27 square meters.

The problem of surface area.
The perimeter of the floor is multiplied by the height of the tile to be tiled by 1 metre, minus the area occupied by the door opening.
-
long, you can put 8 100 2 = 400 pcs.
wide, you can put 6 100 2 = 300 pcs.
high, you can put 5 100 2 = 250 pcs.
A total of 400 300 250 = 3000 0000 = 30 million.
-
The surface area of the warehouse is 2 (length and width) + 2 (length and height) + 2 (width and height) - the area of the door.
Warehouse area = 2 (20 30) + 2 (20 25) + 2 (25 30) - 2 2
3696 square meters.

50 2 = 25 (pcs).
30 2 = 15 (pcs).
5 2 = 2 (pcs)....1 (m), 25 15 2 = 750 (pcs).
A: There are 750 cube cargo boxes that can accommodate up to 8 cubic meters (with an edge length of 2 meters).
There is a cuboid with a square base and its surface area is 190 square centimeters, and if it is cut into two cuboids from a plane parallel to the bottom surface, the sum of the surface areas of the two cuboids is 240 square centimeters. Find the volume of the original box. >>>More
The side area is 78-15*2=48 (square centimeters).
In addition, the side area is also equal to the circumference of the bottom surface * height (assuming the sides of the box are spread out), so the height of the box is 48 16=3 (cm), so the volume of the box is 15*3=45 (cubic centimeters). >>>More
According to the structure drawing method, the shape is partially formed, and there is no need to draw the inner structure line, and find out the projection position and the shape of the projection. >>>More
In fact, the triple integral is an extension of the first and double integrals. >>>More
A box has 6 faces, up to 4 faces are squares, and up to 4 rectangles have the same faces. >>>More
