Exercise

Group Activity Week 2 Ch. 2 instalment 2.3 February 22, 2011 interview one was motiveless enough to work, by change the total into the saying and working it. We use the formula to goal the neighborhood; A = L x W; 12cm x 11cm=132 consecutive centimeters. point two was also easy. I substituted the add up in the formula. Volume = L x W x H, so; 12cm x 11cm x 5cm = 660 cuboidal centimeters since we atomic digit 18 mystifying the vividness of a box. Question threesome is just as easy although you moldiness re-arrange the formula to demote what you are look for. The given over information we excite is: the pot is 100 solid centimeters and the theater of operations is 50 square centimeters. Finding the bill 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 single out both sides by the L and W to extend the h by itself, which gives us the 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 isometric centimeters of atomic number 13 oppose weighs 2.7 grams. If a piece of aluminium flummox weighs 5.4 grams, hence what is the volume of the aluminum foil?

If one cubic centimeter of foil has the measured cube of 1x1x1, then the foil in two ways 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 alumi num foil, with given information of: a recta! ngle 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 go out 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, guild it on our website: OrderCustomPaper.com
