Generally speaking, when describing the size of a cake, "inch" means inch. So, 10 inch is 25.4 cm. Then, the diameter of 10 inch cake is about 25 cm, which is enough for 5-8 people. ?
Extended data:
The diagonal length of 1 and 10-inch square cakes is: 10X2.5 (about 2.5cm per inch, about 25cm. The size of a square cake is measured by the diagonal, because the diagonal is the longest, and this length can only fit into a 10 inch cake box. ) width, because it is a square, it can be converted by trigonometric function sin45 (square, diagonal and two sides form an isosceles right triangle, and the included angle between diagonal and side is 45 degrees), that is, the width = 25x0.7 1 = 17.75cm or so.
2. A 10 inch cake is about 25cm in diameter. Because the bottom embryo of the cake is baked in a standard size cake mold, the diameter of the cake is above 25 cm. Once it is made into a finished product such as cream cake, its diameter will be larger, and it will increase by more than 1 ~ 2 cm depending on plastering and decoration, which is enough for 5-8 people.
