Figure 192 by 288 pixels encoded with a palette of 16 colors. How many kilobytes does the drawing take in memory

Figure 192 by 288 pixels encoded with a palette of 16 colors. How many kilobytes does the drawing take in memory without taking into account compression?

N = 16
K = 192 * 288
N = 2 ^ i
i = 4
J = k * i
J = 192 * 288 * 4
mk in 1 byte is 8 bits, then in kbyte there will be 8 * 1024 bits, in other words it can be written as powers of 2: 2 ^ 3 * 2 ^ 10 = 2 ^ 13
(192 * 288 * 3) /2^13=20.25 KB
