scale factor. 18) A scale model has a length of 40cm. The original had a length of 8km. Determine the scale factor. The scale factor between two similar figures is given. The surface area and volume of the smaller figure are given. Find the surface area and volume of the larger figure. 19) scale factor = 1 : 5 SA = 15 yd² V = 30 yd³ 20) scale ...
Scale factor is a number by which the size of any geometrical figure or shape can be changed with respect to its original size. Learn more about how to find the scale factor, uses of scale factor, along with important tips and solved examples on scale factor.
What is a scale factor? A scale factor describes how much a shape has been enlarged. We multiply every side length of a shape by the scale factor to enlarge it. The sizes of the angles do not change. Enlarging a shape by a scale factor greater than 1 will make the shape bigger. E.g. Shape A has been enlarged by scale factor 2 to give shape B .
A scale factor is a ratio between two corresponding sides of similar shapes. A scale factor describes how much a shape has been scaled up or down. To scale a shape up or down, you multiply every side length of a shape by the scale factor to increase or decrease the size. The sizes of the angles do not change.

Unit 1, Lesson 5: The Size of the Scale Factor 1. Rectangles P, Q, R, and S are scaled copies of one another. For each pair, decide if the scale factor from one to the other is greater than 1, equal to 1, or less than 1. 2. Triangle S and Triangle L are scaled copies of one another. a. from P to Q b. from P to R c. from Q to S d. from Q to R e ...
A scale factor is the ratio between the size of an original and final object that vary only in size. For example, the penguin shown on the left below is 3 times larger than the penguin on the right. The factor we would scale the larger penguin by to get the smaller penguin is the scale factor.
