4. Surface Areas and Volumes of Similar Solids
Sign In
Similar solids are solids that have the same shape and proportional corresponding dimensions.
Yes
We want to know if these two solids are similar. Similar solids have the same shape and proportional corresponding dimensions. Therefore, to determine whether the cones are similar, we will calculate the ratio between corresponding lengths.
Ratio | Substitute | Simplify |
---|---|---|
Length of base of the bigger pyramid/Length of base of the smaller pyramid | 10/5 | 2 |
Width of base of the bigger pyramid/Width of base of the smaller pyramid | 10/5 | 2 |
Height of the bigger pyramid/Height of the smaller pyramid | 12/6 | 2 |
Slant height of the bigger pyramid/Slant height of the smaller pyramid | 13/6.5 | 2 |
The ratio between corresponding lengths is 2. Therefore, the pyramids are similar.
