Pyramid X is similar to pyramid Y. The surface area of pyramid X is 135 square centimeters. The surface area of pyramid Y is 240 square centimeters. If the volume of pyramid X is 189 cubic centimeters, what is the volume of pyramid Y?

294 cubic centimetres

Step-by-step explanation:

if both are similar then you take 240(pyramid y) -135(pyramid x) = 105(difference between the two) then take 189(pyramid x)+ 105 = 294

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
