Question

Two similar pyramids have base edges 3 and 5. Find the following (use a colon between the numbers):

Answer 1

A) 3 : 5

b) 9 : 25

c) 3 : 5

d) 27 : 125

e) 9 : 25

Because the pyramids are similar, any lengths will have the same ratio, areas the ratios squared and volumes cubed.
(You do not need to know their exact shapes or the formulae for the areas or volume.)
