Question

Мистер Фокс решил изготовить сувенир массой 7 г, который состоит из платины плотностью 21,4 г/см3 и дерева плотностью 0,4 г/см3. Данное изделие не должно содержать полостей и тонуть в воде. Один грамм дерева стоит 1 руб., а один грамм платины стоит 1776 руб. Найдите наибольшую суммарную стоимость материалов изделия. Ответ выразите в рублях, округлив до целых.

Calculating the Total Cost of the Souvenir

To find the largest total cost of the materials for the souvenir, we need to calculate the total cost of the platinum and wood that make up the souvenir.

The total cost of the platinum can be calculated using the formula: Total cost of platinum = (mass of platinum) * (density of platinum) * (cost per gram of platinum)

The total cost of the wood can be calculated using the formula: Total cost of wood = (mass of wood) * (density of wood) * (cost per gram of wood)

The largest sum of these two costs will give us the maximum total cost of the materials for the souvenir.

Calculating the Total Cost of Platinum

Given: - Mass of platinum = 7 g - Density of platinum = 21.4 g/cm³ - Cost per gram of platinum = 1776 rubles

Using the formula: Total cost of platinum = (7) * (21.4) * (1776)

Calculating the Total Cost of Wood

Given: - Mass of wood = Total mass of the souvenir - Mass of platinum - Density of wood = 0.4 g/cm³ - Cost per gram of wood = 1 ruble

Using the formula: Total cost of wood = (Total mass of the souvenir - 7) * (0.4) * (1)

Finding the Maximum Total Cost

We will calculate the total cost of platinum and wood separately and then compare the two to find the largest sum.

Let's calculate the total cost of platinum and wood and find the largest sum.
