Pyramid x is similar to pyramid y. The surface area of pyramid x is 135 cm² and the surface area of pyramid y is 240 cm². if the volume of pyramid x is 189 cm³. then what is the volume of pyramid y?
A. 448 cm³
B. 336 cm³
C. 1061.9 cm³
D. 252 cm³

B. 336 cm^3

Step-by-step explanation:

Set up a proportion: 135/x=240/y

135/189=240/y

135y=45360

y=336

Therefore, B. 336 cm^3
