The ratio of their surface area is given by:
9:64
Step-by-step explanation:We know that if two solids are similar such that the ratio of their sides or edges is given by:![\dfrac{a}{b}](/tpl/images/0311/5029/42e28.png)
Then the ratio of the surface area of the two solids is given by:
Here we have:
Hence, on squaring both side of the equality we obtain:
Hence, the ratio of the surface area of two similar solids is:
9:64
