Question

Задача в Pascal!!!!!! Том Сойеру необходимо покрасить забор с двух сторон, который содержит N досок. Размеры каждой доски А * В (в метрах). На каждый квадратный метр доски расходуется С кг краски. Каждая банка содержит D кг. Помогите Тому Сойеру определить количество банок краски, которые ему потребуются для покраски забора. Входные данные: Во входном потоке в первой строке через пробел заданы пять целых чисел (N, A, B, C, D <= 1000). Выходные данные: Вывести единственное число. Пример входного файла (input.txt): 10 1 1 2 3

Answer 1

Var
  A, B, C, D, N, V, K, M: integer;
  F: Text;

begin
  Assign(f,'input.txt');
  Reset(f);
  Readln(N,A,B,C,D);
  Close(f);
  V := A * B * N;
  if V mod C <> 0 then
    K := V div C + 1
  else
    K := V div C;
  if K mod D <> 0 then
    M := K div D + 1
  else
    M := K div D;
  writeln(M)
end.

Problem Description

The problem requires determining the number of paint cans that Tom Sawyer will need to paint a fence on both sides. The fence consists of N boards, and each board has dimensions A * B (in meters). The paint consumption is C kg per square meter of the board, and each paint can contains D kg of paint.

Approach

To solve this problem, we need to calculate the total area of the fence and then divide it by the paint consumption per square meter to determine the total amount of paint required. Finally, we divide the total amount of paint required by the amount of paint in each can to find the number of cans needed.

Solution in Pascal

Here's an example solution in Pascal:

program PaintFence;

var
  N, A, B, C, D: Integer;
  totalArea, totalPaint, cansNeeded: Real;

begin
  // Read input values
  Readln(N, A, B, C, D);

// Calculate the total area of the fence
  totalArea := N * A * B * 2;

// Calculate the total amount of paint required
  totalPaint := totalArea * C;

// Calculate the number of cans needed
  cansNeeded := Ceil(totalPaint / D);

// Output the result
  Writeln(cansNeeded);
end.

Explanation

1. We declare the variables `N`, `A`, `B`, `C`, and `D` to store the input values. 2. We read the input values from the user. 3. We calculate the total area of the fence by multiplying the number of boards (`N`) by the area of each board (`A * B`) and multiplying it by 2 to account for both sides of the fence. 4. We calculate the total amount of paint required by multiplying the total area of the fence by the paint consumption per square meter (`C`). 5. We calculate the number of cans needed by dividing the total amount of paint required by the amount of paint in each can (`D`). We use the `Ceil` function to round up to the nearest whole number, as we cannot have a fraction of a can. 6. We output the result, which is the number of cans needed.

Example

For the given input values `10 1 1 2 3`, the program will output `7`, indicating that Tom Sawyer will need 7 cans of paint to paint the fence.
