## What is the scale factor of two similar pyramids?

We can use this pair of lengths in order to work out the scale factor for the lengths between the two pyramids. By dividing the larger length by the smaller, we have that the length scale factor or LSF between the two pyramids is 10 divided by five, which is two.

## What does it mean when two prisms are similar?

Recall that two shapes are similar if all the corresponding angles are congruent and the corresponding sides are proportional.

**How do you calculate scale factor?**

The basic formula that is used for calculating the scale factor is, Scale factor = Dimension of the new shape ÷ Dimension of the original shape. In case, if the original figure is scaled up, the formula is written as, Scale factor = Larger figure dimensions ÷ Smaller figure dimensions.

**What is the scale factor of similar solids?**

When two solids are similar, their corresponding dimensions are proportional. The ratio of the corresponding dimensions of similar solids is called the scale factor. All the linear dimensions (length, width, and height) of a solid must have the same scale factor for the solids to be similar.

### What is scale factor and how it is used in similar solids?

The ratio that you get when you divide corresponding side lengths of similar figures is called the scale factor. In the last example, the ratios all simplified to 3/4 so we would say that the scale factor of triangle LMN to triangle QRS is 3/4. Another way to describe a scale factor is that it’s a multiplier.

### How is the scale factor between two similar solids related to the ratio of the surface area of the solids and to the ratio of the volumes of the solids?

Surface Areas of Similar Solids In two dimensions, when two shapes are similar, the ratio of their areas is the square of the scale factor.

**What is a scale factor of 2?**

The size of an enlargement/reduction is described by its scale factor. For example, a scale factor of 2 means that the new shape is twice the size of the original. A scale factor of 3 means that the new shape is three times the size of the original.

**What is a dilation with a scale factor of 2?**

Dilation Scale Factor 2: If the scale factor is 2, then every coordinate point of the original triangle is multiplied by the scale factor 2. Therefore, the dilated triangle will be A’B’C’ and the coordinate points obtained are A'(0, 4), B'(4, 2), C'(-4, -4).

## When two solids are similar the ratio of their volumes equals the ratios of their corresponding lengths cubed?

If two solids are similar, the ratio of their volumes is equal to the cube of the ratio of their corresponding sides. (Note that volume is not a “length” measurement – it is a 3-D measurement.)

## How do you dilate a scale factor of 2?

To dilate the figure by a factor of 2, I will multiply the x and y-value of each point by 2. I plotted all the new points to find the new triangle. To dilate the figure by a factor of 2, I will multiply the x and y-value of each point by 2.

**How do you enlarge by a scale factor of 2?**

To enlarge a shape, multiply all lengths of the shape by the scale factor. The scale factor tells us how many times larger the shape will be. For example, enlarging a shape by scale factor 2 means that all of the sides will become 2 times longer. This rectangle is 1 square wide and 2 squares long.

**Is a dilation with a scale factor of 2 A reduction?**

It’s a reduction; the scale factor is 2.
