Halfway there. two square pyramids have the same volume. for the first pyramid, the side length of the base is 16 in and the height is 28. on the 2nd pyramid the height is 112. what is the side length of the base of the 2nd pyramid? ,

Given:

h = height 
s = slant height
a = side length
e = lateral edge length
r = a/2 
V = volume
L = lateral surface area
B = base surface area 
A = total surface area

Pyramid 1. 

h = 28 m
s = 29.1204 m
a = 16 m
e = 30.1993 m
r = 8 m
V = 2389.33 m³
L = 931.854 m2
B = 256 m²
A = 1187.85 m²
Pyramid 2 

h = 112 m
s = 112.071 m
a = 7.99999 m
e = 112.143 m
r = 3.999995 m
V = 2389.33 m³
L = 1793.14 m²
B = 63.9999 m²
A = 1857.14 m²
