About this worksheet

Similar solids and changing dimensions. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

  • I can grow a length by k, an area by k × k and a volume by k × k × k.
  • I can find the scale factor from two volumes or two areas.
  • I can tell what a change in only the radius or only the height does to a volume.

Standard: G-GMD.A.3 (related), G-SRT.A.2

Words to know

similar solids: The same shape, with every length multiplied by one number.

scale factor (k): The number every length is multiplied by.

cube root: The number used three times to make it: the cube root of 64 is 4.

Common mistakes

Your child multiplied a length by the scale factor twice.

Your child added the scale factor instead of multiplying by it.

Your child grew an area or a volume by the scale factor only once. Draw a 1 by 1 square and double its sides: how many small squares fit now?

What to say

Ask: if a photo is made 3 times as wide, how many times as long is each edge?

Ask: is a copy 3 times as tall 3 more or 3 times as much?
