How can you determine if two solids are similar?

• By comparing their colors

• By checking if they have the same volume

• By using corresponding dimensions

• By measuring their weights

If two triangles have sides in the ratio 3:1, what does this indicate?

• The triangles are congruent

• The triangles are different shapes

• The triangles are similar

• The triangles are identical

What is the key step in finding the surface area of similar solids?

• Using the cube of the ratio of linear measures

• Using the square of the ratio of linear measures

• Adding the areas of all faces

• Subtracting the areas of the bases

When calculating the surface area of similar solids, what must you remember to do?

• Cube the side lengths

• Square the side lengths

• Double the side lengths

• Halve the side lengths

What is the relationship between the volume of similar solids and their corresponding linear measures?
