Question 1060446
"Another block", how?  Are the two blocks supposed to be similar?  Assuming that they are ,
and also expect that the density of the two blocks will be equal.


volume is directly proportional to mass.


{{{((217)/(20*15*8))(pounds/(in*in*in))=((13888)/(20*k*15*k*8*k))(pounds/(in*in*in))}}}


k is a factor applied to each dimension.  Solve for k in the equation and then find each of the three dimensions using k.
