V = l x w x h (V = lwh)

8 x 4 x 6 = 192

750cm³ = 10 cm x 5 cm x 15 cm (V = l x w x h)
|
72 cm = 6 cm x 4 cm x 3 cm (V = l x w x h)

10 x 3 x 4 = 120 so 5 x 4 x ? = 120
5 x 4 = 20 so 20 x ? = 120 120 ÷ 20 = 6 |
The cube root of 125 = 5 because 5 x 5 x 5 = 125

50 cm x 60 cm x 80 cm = 240,000 cm3. Then divide by 1,000 as 1 litre = 1,000 cm3
|
1 litre = 1,000 cm3. Each of the smaller boxes has a volume of 1 litre

Work out the are of the circle on a cylinder using ? r2 then times by the length of the cylinder
|
60 cm diameter = 30 cm radius. 302 = 900. 900 x 3.142 (?) = 2,827.8 Multiply this by 88 (height or length) = 248,846 cm3 or approximately 249 litres
