Ratio of their volumes = a³ : b³
Ratio of their surface areas =
<u>Step-by-step explanation:</u>
Two square pyramids are similar with their edges are in the ratio of a : b.
Volume of a square pyramid with edge and h = a is given by the formula,
= =
Volume of a square pyramid with edge b and h = b is given by the formula,
= =
Ratio of their volumes = a³ : b³ since h/3 gets cancelled.
Total surface area of square pyramid with the edge a =
Total surface area of square pyramid with the edge b =
Ratio of the surface area =
