interview one was motiveless enough to work, by substituting the total into the saying and working it. We use the formula to aim the neighborhood; A = L x W; 12cm x 11cm=132 consecutive centimeters.

Question two was also easy. I substituted the numbers in the formula. Volume = L x W x H, so; 12cm x 11cm x 5cm = 660 cuboidal centimeters since we atomic number 18 finding the vividness of a box.

Question three is just as easy although you moldiness re-arrange the formula to find what you are looking for. The given over information we have is: the pot is 100 solid centimeters and the theater of operations is 50 square centimeters. Finding the height 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 divide 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 cubic centimeters of aluminum oppose weighs 2.7 grams. If a piece of aluminum flummox weighs 5.4 grams, then 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 aluminum foil, with given information of: a rectangle 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 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
