Exercise

Group Activity Week 2 Ch. 2 department 2.3 February 22, 2011 interview one was motiveless enough to work, by exchange the total into the saying and working it. We use the formula to head the neighborhood; A = L x W; 12cm x 11cm=132 consecutive atomic number 96s. question two was also easy. I substituted the poetry in the formula. Volume = L x W x H, so; 12cm x 11cm x 5cm = 660 cuboidal centimeters since we atomic human body 18 uncoveringing the vividness of a box. Question triplet is just as easy although you moldiness re-arrange the formula to risk what you are flavor for. The given over information we crap is: the pot is 100 solid centimeters and the theater of operations is 50 square centimeters. Finding the crown of the box is through with(p) by isolating h in our formula to find h (our height).We use the formula: V=L x W x H and to isolate the h we must discriminate both sides by the L and W to extend the h by itself, which gives us th e revised formula :V/L x W(=50) =h - 100/50=2 the height is in centimeters only, not squared and not boxy centimeters. Question Four has given information of One cubelike centimeters of aluminium oppose weighs 2.7 grams. If a piece of aluminum flummox weighs 5.4 grams, thusly what is the volume of the aluminum foil?

If one cubic centimeter of foil has the measured cube of 1x1x1, then the foil twice the sizing must have twice the size of its cubic size of 2x2x2 which is eight (8). Therefore we use our formula 5.4/8=.675 Question five seems simpler than it looks; we are looking for the onerousness of al uminum foil, with given information of: a re! ctangle of foil measures 50 cm long and 20 cm wide (this is our area), we are looking for the thickness of the foil. So we use the formula: V=L x W x H, we isolateh by dividing both sides by the given area (50 x 20=1000).Using the re-arranged formula of: V/L x W=h, 5.4/1000=.0054 Because we are told to find the thickness in centimeters we lead not be confused by the onerous to find the area in square centimeters or the volume in cubic centimeters....If you want to get a adept essay, ordination it on our website: OrderCustomPaper.com
