    The area of the four walls and ceilings is 28 + 48 = 76 (m 2) 76 * 2 4 = 38 (kg).

    38*4=152 (yuan).

    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.

    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.

    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.
