d) have less material (surface area)
(PLEASE PROVIDE ANSWER WITH AN EXPLANATION TO WHY)
thanks so much!

Answer 1

c less material surface area

Answer 2

well, since same volume of salt, that means the amounts are the same

lets test a sample cube

if the volume is 64
cube side legnth is 4 each side
SA=96

a rectangular prism with volume of 64 could be
1 by 1 by 64
SA=2(LW+LH+WH)
SA=2(1+64+64)
SA=2(128)
SA=256

256>96

cube has less surface area

D is teh answer
