Question

Гранитная глыба для памятника "Медный всадник" до обработки имела массу 1600 тонн. Сколько колонн объемом 4 куб. метра можно было изготовить из такой массы гранита? (плотность гранита = 2600 кг/куб. м ; 2,60 г/куб. см)

Answer 1

m=V*P

V=m/P

V=1600000/2600=615.4 (м^3) - общий объем глыбы

615/4=153.85, т.е. можно изготовить 153 колонны

Answer 2

Calculation of the Number of Columns

To calculate the number of columns that can be made from a granite block weighing 1600 tons, we need to convert the mass of the block to kilograms and then divide it by the volume of each column.

Given: - Mass of the granite block: 1600 tons - Density of granite: 2600 kg/m³

To convert the mass of the granite block from tons to kilograms, we multiply it by 1000: - Mass of the granite block in kilograms: 1600 tons * 1000 kg/ton = 1,600,000 kg

Now, we need to calculate the volume of each column. The volume of a column can be calculated using the formula:

Volume = Length * Width * Height

However, the dimensions of the columns are not provided in the question. Therefore, we cannot determine the exact number of columns that can be made from the given mass of granite.

Please provide the dimensions (length, width, and height) of each column so that we can calculate the number of columns.
