King Henry doesn't mind drinking chocolate milkKing = kmHenry = hmdoesn't = dammind = mdrinking = dmchocolate = cmmilk = mm Volume - the amount a 3D shape can hold (how much can go inside) Volume of a Rectangle V = Length x Width x Height Volume of a Triangular Prism V = base x height divided by 2 Perimetre -the distance around a particular object Perimetre of a Rectangle P = (length + width) x 2 OR P = 2L + 2W Perimetre of a Triangle P = side 1 + side 2 + side 3 mm to cm...what do you do? divide by 10 e.g. 150 mm = 15 cm cm to m...what do you do? divide by 100 e.g. 200 cm = 2 m m to km...what do you do? divide by 1000 e.g.  3500 m = 3.5 km Surface Area -the area of all the faces of a 3D shape added up all together -use the area of rectangle (L x W) and the area of a triangle (B x H divided by 2) for these calculations km to m x 1000 e.g. 5 km = 5000 m m to cm x 100 e.g. 4.5 m = 450 cm cm to mm...what do you do? x 10 e.g. 17 cm = 170 mm mL to L ...what would you do? divided by 1000 e.g. 35000 mL = 35 L L to mL...what do you do x 1000 e.g. 72 L = 72 000 mL For King Henry doesn't mind drinking chocolate milk...how does it work? - if moving down the ladder you x 10 for each step - if moving up the ladder you divide by 10 for each step 10 cm = ______ mm x 10 So, 10 cm = 100 mm 100 m = _____ km -divided by 1000 So, 100 m = 0.1 km 5650 mm = _____ m -go up the ladder 3 times So, divide by 10, then divide by 10, then divide by 10 So, 5650 mm = 5.65   78 km= _______ hm -move down the ladder 1 time So, x 10 So, 78 km = 780 hm 4820 cm = _____ dm -move up the ladder 1 time -So, divide by 10 -So, 4820 cm = 482 dm 78 569 mL = ______ L -divide by 1000 So, 78 569 mL = 78.569 L 982 767 cm = ______ m - move up the ladder 2 times -so divide by 10, then divide by 10 again -So, 982 767 cm = 9827.67 m What type of measurement would you use to measure a fingernail? -mm would be most accurate -could use cm What type of measurement would you use to measure the distance between Hamilton and Florida? -km -it is the longest measure of distance and it is a long way from Hamilton to Florida What measurment would you use to measure the height of a tree? -metres -dam (a decametre is 10 metres) What measurement would you use to measure the length of a desk? -cm would be most accurate -mm would be extremely accurate but take too long What unit of measure would you use to determine the distance from your house to school? -it depends on how far away you live -if you live across the street you might choose metres -if you want at least 10 minutes you might want to use dam, hm, or km What unit of measurement would you use to find the amount of water in a swimming pool? -Litres AuthorMrs.Pollock ID242223 Card SetMeasurement DescriptionMeasurement terms Updated2013-10-22T23:35:40Z Show Answers
