The two solids below are similar, and the ratio between the lengths of their edges 4: 7 what is the ratio of their surface areas

16: 49

Step-by-step explanation:

If two shapes are similar , then the following condition holds

(i) the ratio of their sides are equal

(ii) If is the length of the first one and is the length of the second one then:

=

Where A stands for the area

(iii)   =

Following theses conditions , the ratio of the lengths of their edges is given to be 4 : 7 , then the ratio of their surface area implies:

=

= 16/49

Therefore the ratio of their surface area is 16: 49
