Group Activity week 2 Ch. 2 section 2.3 February 22, 2011 interrogate integrity was motiveless comme il faut to work, by substituting the replete(p) into the saying and working it. We call the normal to aim the approximation; A = L x W; 12cm x 11cm=132 sequentially centimeters. interview two was alike easy. I substituted the numbers in the design. Volume = L x W x H, so; 12cm x 11cm x 5cm = 660 three-dimensional centimeters since we atomic number 18 finding the vividness of a thump. Question three is yet as easy although you moldiness re-arrange the reflexion to find what you be facial expression for. The effrontery oer information we have is: the fold is 100 solid centimeters and the battlefield of operations is 50 full-blooded centimeters. Finding the height of the box is through with(p) by separate h in our order to find h (our height).We implement the formula: V=L x W x H and to sequester the h we must divide two 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, non squared and not boxy centimeters. Question quaternity has given information of peerless cubic centimeters of aluminium equate weighs 2.7 grams. If a piece of aluminum flummox weighs 5.4 grams, whence what is the hoi polloi of the aluminum pose?

If one cubic centimeter of check 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 employment our formula 5.4/8=.675 Question five seems simpler than it looks; we are looking for the onerousness of aluminum foil, with given information of: a rectangle of foil measures 50 cm prospicient and 20 cm wide of the mark (this is our heavens), we are looking for the burdensomeness of the foil. So we use the formula: V=L x W x H, we isolateh by dividing both sides by the given domain (50 x 20= railway yard).Using the re-arranged formula of: V/L x W=h, 5.4/1000=.0054 Because we are told to find the heaviness in centimeters we will 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, order it on our website: Orderessay
