At 300 dpi resolution, 3.5 cm x 1.5 cm is equivalent to 413 x 177 pixels.
Explanation:
Given, the dimensions are 3.5 cm x 1.5 cm
Since, 1 inch = 2.54 centimeters
(3.5/2.54)=1.378
(1.5/2.54)=0.59
3.5 cm x 1.5 cm is equal to 1.378 in x 0.59 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 pixel dimensions can be calculated as follows: 1.378 x 300 x 0.59 x 300 pixels = 413 x 177 pixels.
