3.5 cm x 4.5 cm is equivalent to 413 x 531 pixels at 300 dpi.
Explanation:
Given, the dimensions are 3.5 cm x 4.5 cm
Since, 1 inch = 2.54 centimeters
(3.5/2.54) = 1.378 inch
(4.5/2.54) = 1.77 inch
3.5 cm x 4.5 cm is equal to 1.378 in x 1.77 inch
According to, the given dpi (dots per inch or pixels per inch) is 300 which means there are 300 dots or pixels in 1 inch.
Therefore, the dimensions in pixels are 1.378 x 300 x 1.77 x 300 pixels = 413 x 531 pixels.
