V=LWH
small=12*8*4=384
large=20*15*9=2700
space=large-small
space=2700-384
space=2316
there is 2316in^3 left
Answer: a = 8
Step-by-step explanation:
Volume of a square based pyramid is given as
.
where a is the length of the side and h is the height.
Substituting into the formula , we have
V = 
128 =
/3
384=
X 6
Divide through by 6
384/6 = 
64 = 
Therefore :
a = 
a = 8
