Final answer:
The size of an image with dimensions of 1920 by 1080 pixels using bitmap representation and 3 bytes per pixel (1 byte for each primary color) is approximately 6.22 megabytes.
Step-by-step explanation:
The size of a picture that is 1920 by 1080 pixels with a bitmap representation using 1 byte for each primary color is determined by calculating the total number of pixels and then multiplying it by the number of bytes used per pixel. Since each pixel uses 1 byte for red, 1 byte for green, and 1 byte for blue, this is a total of 3 bytes per pixel.
First, we find the total number of pixels by multiplying the width and the height:
1920 pixels (width) × 1080 pixels (height) = 2,073,600 pixels.
Then we multiply the total number of pixels by the number of bytes per pixel:
2,073,600 pixels × 3 bytes/pixel = 6,220,800 bytes.
Divide by one million to convert bytes to megabytes (MB):
6,220,800 bytes ÷ 1,000,000 = 6.22 MB.
Therefore, the image requires approximately 6.22 MB to be stored.
