10 ! determine the pressure of your book in pascals (pa). show your work! (the pressure of the book in psi is 0.03 psi) also the weight of the book is 3 lbs
hint: 1 pa = 1 n/m^2 weight (force) = ma 1 kg = 2.2 lbs 1 inch = 2.54 cm 1m = 100 cm

You've listed a lot of data here, in both metric and customary units,
and I'm not even sure it's all needed.  Let me try and boil it down:

Pressure on a surface =
               (total force on a surface) divided by (area of the surface).

The answer to the question is the pressure expressed in pascals. 
There's actually enough information here to answer the question
in 2 different ways.  We could ...

-- simply convert (0.03 pound per inch²) to pascals, or
-- go through the whole calculation of force, area, and then their quotient. 

To me, converting 0.03 psi to Pa looks easier.

-- 1 pascal = 1 newton / 1 meter²

-- On Earth, 1 kilogram of mass weighs 9.8 Newtons and 2.2 pounds.
From this, we can calculate that

                    2.2 pounds of force = 9.8 newtons of force.

                     1 pound = 4.45 newtons

(0.03 pound/inch²) x (4.45 newton/pound) x (1inch/2.54cm)² x (100cm/1m)² =

 (0.03 x 4.45 x 1² x 100²) / (2.54² x 1²)    newton/meter²  =  206.9 Pa .

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
