The volume of square pyramid of base edge 5 m and height 12 m is (in cubic centimetres) :
75
64
100
90
Volume of a square pyramid = 13×Base area×Height Thus, Volume = 13×5×5×12=100
The base edges of two square pyramid are in the ratio 1 : 2 and their heights are in the ratio 1 : 3. The volume of the first pyramid is 180 cubic centimetres. What is the volume of the second?
