#include <iostream>
#include <math.h>
#define divideByte 8
#define sizeSection 1024
 
using namespace std;
 
int main (void)
{
    int SamplingRate = 0;
    int QuantizationRate = 0;
    int ChannelNum = 0;
    int Second = 0;
    unsigned int fileSize = 0;
    double megaFileSize = 0;
    cin >> SamplingRate >> QuantizationRate >> ChannelNum >> Second;
    
    fileSize = (SamplingRate * QuantizationRate * ChannelNum * Second);
    megaFileSize = fileSize / (double)divideByte / pow((double)sizeSection, 2.0);
    cout << fixed;
    cout.precision(1);
 
    cout << megaFileSize << " MB" << endl;
    
    return 0;
