If the volume for 3-D polyhedra A is 200 cm3 and the volume for 3-D polyhedral B is 800 cm3, how many times bigger is the volume of pyramid B than pyramid A?

B is 4x bigger than A

Step-by-step explanation:

-This is a question testing proportionality.

#We first get the ratio the ration of the volumes as

We then express it in the equation form of constant of proportionality  y=kx, where k is the constant of proportionality:

Hence, B is 4 times the volume of A

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !
