Volume? The space a 3D shape takes up tells you how much a container will hold
Volume of a cuboid Depends on How long it is h How wide it is b How high it is l Volume = length X breadth X height v = lbh
5cm 4cm 10cm v = lbh = 10 X 4 X 5 = 200cm3 = 200ml remember 1000ml = 1 litre
You Try 2. 1. 4cm 48cm3 8cm 160cm3 2cm 4cm 6cm 5cm 4. 3. 5cm 7cm 120cm3 350cm3 3cm 8cm 5cm 10cm
Compound Volumes 3cm 10cm 6cm 4cm 11cm
Compound Volumes 3cm 4cm 11 X 3 X 4 = 132cm3 10cm 11 X 4 X 6 = 264cm3 6cm 6cm 4cm 11cm 11cm Total volume = 396cm3
