M1.64
! For 2m, condone 63.99(…) (some calculator
displays will show this as their final answer)
2
or
Shows the value 19 200 (volume of the tank)
OR
Shows or implies a complete correct method, eg:
•
(40 × 40 × 12) ÷ 300 = 58 (error)
! For 1m, condone 63.9 as evidence of an
appropriate method (calculator display
incorrectly rounded)

M2.
Award TWO marks for the correct answer of 5cm
If the answer is incorrect award ONE mark for evidence of an
appropriate method, eg
2n × n × n = 250
so
n × n × n = 125
The calculation need not be completed for the award of the
mark, but n × n × n = 125 OR n3 = 125 must be reached.
