How many millilitres is this? The shallow plastic tray is used to fill the bucket with water. How many litres of waste can it hold when full? 4 30 cm 60 cm 50 cm 8.
#LIGHTWRIGHT 6 HOW TO CHANGE STOCK AMOUNT FULL#
This tank is half full of water This lead-lined box is used to store liquid radioactive waste. How many ingots like this must be melted down to make this gold bar? 6 What will the total weight of the bar be if 3 of gold weighs 19 3 grams? 11. This little ingot of gold is in the shape of a cube of side 0.
Remember : to change from:- litres > millilitres you simply x Change each of the following to millilitres : 5 litres 9 litres 17 litres 8 5 litres (e) 2 3 litres (f) 19 5 litres (g) 0 4 litres (h) 0 35 litres (i) 0 08 litres. Remember : to change from:- millilitres > litres you simply Change each of the following to litres : 4000 ml 8000 ml ml 6500 ml (e) 1200 ml (f) ml (g) 700 ml (h) 200 ml (i) 15 ml. How many litres of oil will each of these tanks hold when full? cm 50 cm 1 70 cm cm cm 50 cm 1 Chapter six page 48 Volumeĥ 5.
How many millilitres of oil will it hold? What is its capacity in litres? 4. Calculate the capacity of each of these containers when full of liquid : cm Calculate its volume in cm 3. If it is filled with water, how many millilitres will it hold? 2. Exercise Calculate the volume of this cuboid in cm This metal tank is to be filled to the top with oil. If filled with water, we say its CAPACITY is 1000 ml or 1 litre. Its volume is given by :- V = L x B x H = 10 x 10 x 10 = 1000 cm 3. 3 = 1 millilitre = 1 ml So a carton of milk might hold 567 ml and a bottle of raspberry juice 330 ml. When discussing liquids, we refer to this as 1 millilitre. If we fill it with water, it will hold 3. Look at this hollow cube with sides long.
Volume = Chapter six page 47 VolumeĤ Volumes of Liquids - Capacity When talking about the volumes of liquids, we do NOT talk about buying 56 3 of milk, or drinking a 330 cm 3 bottle of beer. Calculate the H, L or B in these cuboids :- H cm Volume = 80 cm 3. How many cubes are there on the top layer? h cm Calculate what the height (h cm) of the cuboid must be. Find the volumes of these shapes : Repeat for this shape consisting of a yellow and a green cuboid Find the volumes of these shapes consisting of 2 or more cuboids :- 10. Copy and complete :- Volume (blue) Volume (red) = L x B x H = 5 x 4 x 3 =. This shape consists of a blue cuboid on top of a pink one. Calculate the volume of each of these cubes :- 1 Chapter six page 46 Volume 3ģ 6. Use the above formula to calculate the volume of each of these cuboids :- 5. cm 3 (Check each answer by counting cubes). Copy and complete :- Vol = L x B x H V = 7 x 7 x 7 V =. In a cube, all of the edges are the same length.
The same formula can be used to calculate the volume of a cube. Use the above formula to calculate the volumes of these cuboids :- (Show 3 steps each time). Volume = length x breadth x height or in symbols V = L x B x H Exercise Copy and complete :- 3. The top layer consists of 4 rows of 3 cubes => 4 x 3 (= 3 ) There are 2 identical layers => Volume = 2 x (4 x 3) (= 2 3 ) This means a simple process to determine the volume of a cuboid (or cube) is to multiply the 3 dimensions. (e) (f) (e) (f) (g) (h) (g) (h) Chapter six page 45 VolumeĢ Volume - Cubes & Cuboids - a Formula Look at the cuboid on the right and find out if we can determine its volume without having to count it cube by cube. cm Write down the volumes of each of these shapes. By counting the number of cubes on the top face, calculate and write down the volume of each of the shapes in cubic centimetres (cm 3 ). Exercise How many centimetre cubes does this shape contain? 3. A small cube which measures by by is said to have a volume of 1 cubic centimetre and is written as 3. 3 The basic unit of volume is the cubic centimetre. 1 Chapter 6 Volume Volume by Counting Cubes The volume of a shape is the amount of space it takes up.
