Answer 1

Переведем в метры; 1)0,25*0,12*0,06=0,0018 м^3 объём кирчича; 2)72:0,0018=40000 шт кирпичей привёз грузовик

Answer 2

Calculation of the Number of Bricks

To calculate the number of bricks that the truck brought to the construction site, we need to determine the volume of the bricks and then divide the total volume of bricks delivered by the volume of a single brick.

Given: - Length of the brick: 25 centimeters - Width of the brick: 12 meters (converted to centimeters, it is 1200 centimeters) - Thickness of the brick: 6 centimeters - Total volume of bricks delivered: 72 cubic meters

To calculate the volume of a single brick, we multiply the length, width, and thickness:

Volume of a single brick = Length x Width x Thickness Volume of a single brick = 25 cm x 1200 cm x 6 cm

Now, let's calculate the volume of a single brick:

Volume of a single brick = 25 cm x 1200 cm x 6 cm = 180,000 cubic centimeters

To convert the total volume of bricks delivered to cubic centimeters, we multiply by 1,000,000:

Total volume of bricks delivered = 72 cubic meters x 1,000,000 cubic centimeters/m^3 = 72,000,000 cubic centimeters

Now, we can calculate the number of bricks:

Number of bricks = Total volume of bricks delivered / Volume of a single brick Number of bricks = 72,000,000 cubic centimeters / 180,000 cubic centimeters

The truck brought a total of approximately 400 bricks to the construction site.

Please note that the calculation assumes that there is no space between the bricks and that the bricks are perfectly rectangular.
