Answer:
The volume of pyramid B is 3.5 times greater than the volume of pyramid A
Step-by-step explanation:
The area of squared based a pyramid is given by:

Where 's' the length of the side of the base and 'h' is the height.
For pyramid A:
h= 100 m
s= 356/4 = 89 m

For pyramid B:
h= 215 m
s= 456/4 = 114 m

Pyramid B has a greater volume and the ratio between volumes is:

A trapezoid<span> can be drawn on </span>2 <span>dimensional </span><span>surfaces like board. So it is a </span>2D shape.
