The pyramid B is 5 times the pyramid A.
Volume is defined as the space occupied by any object in the three-Dimensions. All three parameters are required for the volume like length, width and height of the cube or cuboid.
The volume of the Pyramid A will be calculated as:-
V = [tex]\dfrac{1}{3}B^2H[/tex]
V = [tex]\dfrac{1}{3}\times 9\times 9\times 10[/tex]
V = 270 cubic inches
Now the volume of the Pyramid B is 1350 cubic inches
The ratio of the volumes will be = [tex]\dfrac{P_B}{P_A}[/tex]
[tex]\dfrac{P_B}{P_A}=\dfrac{1340}{270} = 5[/tex]
PB = 5 PA
Therefore pyramid B is 5 times pyramid A.
