Draw both cis- and trans-1,4-dimethylcyclohexane in their more stable chair conformations

Draw both cis- and trans-1,4-dimethylcyclohexane in their more stable chair conformations. (a) How many stereoisomers are there of cis-1,4-dimethylcyclohexane, and how many of trans-1,4-dimethylcyclohexane? (b) Are any of the structures chiral? (c) What are the stereochemical relationships among the various stereoisomers of 1,4-dimethylcyclohexane?

A trisubstituted cyclohexane compound is given below in its chair conformation. Draw the corresponding planar (overhead) representation, using wedges and hashed bonds to indicate the substituent positions. To be graded properly, include the hydrogen atoms on the chirality centers (asymmetric carbons). Be sure that both wedges/hashed bonds are drawn on the outside of the ring, or else the stereochemistry may be interpreted as square planar.
