<h3>Because </h3><h3>1.5mm =0.15 cm ,</h3><h3>so both covers together would be 0.3 cm , subtract that from 5 cm,i.e.,</h3><h3>5 -0.3 = 4.7 cma book has two covers one at front and at back</h3><h3 /><h3>so 1.5 +1.5 =3 mm</h3><h3 /><h3>so 10 mm = 1 cm</h3><h3 /><h3>convert 5 cm to mm as 5 * 10 = 50 mm</h3><h3 /><h3>50-3 = 47 mm or 4.7 cm</h3><h3>Have a awesome night✨</h3>
