Answer 2

Calculation of Potato Volume in the Basement

To calculate the volume of the basement, we can use the formula for the volume of a rectangular parallelepiped:

Volume = Length x Width x Height

Given the dimensions of the basement: - Length = 18 m - Width = 10.5 m - Height = 1.8 m

We can substitute these values into the formula to find the volume of the basement:

Volume = 18 m x 10.5 m x 1.8 m = 330.75 cubic meters.

Now, we are given that the weight of 5 cubic meters of potatoes is equal to 7.5 metric tons. To find the weight of potatoes that can be filled in the basement, we need to calculate the weight per cubic meter of potatoes:

Weight per cubic meter = 7.5 metric tons / 5 cubic meters = 1.5 metric tons per cubic meter.

To find the weight of potatoes that can be filled in the basement, we can multiply the volume of the basement by the weight per cubic meter:

Weight of potatoes in the basement = Volume of basement x Weight per cubic meter = 330.75 cubic meters x 1.5 metric tons per cubic meter = 496.125 metric tons.

Therefore, approximately 496.125 metric tons of potatoes can be filled in the basement.

Calculation of Bricks for Building a Wall

To calculate the number of bricks required to build a wall, we need to find the volume of the wall and the number of bricks per unit volume.

Given the dimensions of the wall: - Length = 15 m - Thickness = 0.6 m - Height = 1.2 m

We can use the formula for the volume of a rectangular parallelepiped to find the volume of the wall:

Volume = Length x Thickness x Height

Substituting the given values, we get:

Volume = 15 m x 0.6 m x 1.2 m = 10.8 cubic meters.

Now, we are given that to build a wall with dimensions 18 m x 0.8 m x 2.1 m, we need 16,800 bricks.

To find the number of bricks required for the wall with dimensions 15 m x 0.6 m x 1.2 m, we can use the concept of proportionality.

Let's assume the number of bricks required for the wall with dimensions 15 m x 0.6 m x 1.2 m is 'x'.

We can set up the following proportion:

Number of bricks / Volume of wall = 16,800 bricks / 10.8 cubic meters

Simplifying the proportion, we get:

x / 10.8 = 16,800 / 18

Solving for 'x', we find:

x = (16,800 / 18) x 10.8

Calculating this, we get:

x ≈ 10,000 bricks.

Therefore, approximately 10,000 bricks will be required to build the wall with dimensions 15 m x 0.6 m x 1.2 m.

Please note that these calculations are approximate and may vary depending on the specific dimensions and characteristics of the materials used.
