1. The question says 2 pairs of pants, but for some reason you calculated it with 4 pairs of pants.

It's not counted as that. You can only wear a pair of pants, not one "pant" by itself.

Question 1 - Two pairs of pants just means two. A pair of pants means one. So it's 2 x 2 x 2 = 8

Question 2 - I got 81 also. Are you sure you looked at the correct answer?

EDIT: Should probably check replies before I post.

a) l*w +2*(l*d)+2*(w*d)
= 12*3.6 +2*(12*1.6) +2*(3.6*1.6)
=91.12? (check with calc if wrong)

b) l*w*0.2
=8.64m^3

I too received 81 as my answer for the second question (check with your teacher as to why the answer is 36)

Question 2: the answer is 81, draw it out and work it out by hand to double check.
