Question

Кирпич имеет длину 25см.ширину 12см и толщину 6см зв несколько рейсов грузовик привез на стройку 72(м3) кирпичей сколько штук кирпичей привез грузовик

Answer 1

1) 25 • 12 • 6 = 1800 ( см3 ) = 0,0018 ( м3 ) обьем одного кирпича
2) 72 : 0,0018 = 40000 ( штук )

Answer 2

Calculation of the Number of Bricks

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

Given: - Length of each brick: 25 cm - Width of each brick: 12 cm - Thickness of each brick: 6 cm - Volume of bricks delivered: 72 m^3

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 12 cm x 6 cm

Now, we need to convert the volume of the bricks delivered to cubic centimeters (cm^3) to match the volume of a single brick:

1 m^3 = 1,000,000 cm^3

Volume of bricks delivered = 72 m^3 x 1,000,000 cm^3/m^3

Finally, we can calculate the number of bricks delivered by dividing the volume of the bricks delivered by the volume of a single brick:

Number of bricks = Volume of bricks delivered / Volume of a single brick

Let's calculate the number of bricks using the given measurements:

Volume of a single brick = 25 cm x 12 cm x 6 cm = 1800 cm^3

Volume of bricks delivered = 72 m^3 x 1,000,000 cm^3/m^3 = 72,000,000 cm^3

Number of bricks = 72,000,000 cm^3 / 1800 cm^3

The truck delivered approximately 40,000 bricks to the construction site.

Please note that the above calculation assumes that there is no space between the bricks and that the bricks are perfectly stacked without any gaps. In reality, there might be some space between the bricks, so the actual number of bricks delivered may be slightly different.
