A large sack of grain contains 7 kg of grain.

| (3 marks) |
Notes
B3: for \(F = 2r + 7h\) oe
(B2 for \(2r + 7h\) or \(F = 2r + ah\)
or \(F = br + 7h\) or \(F = 2h + 7r\))
(B1 for \(2r + ah\) or \(br + 7h\) or \(2h + 7r\)
or \(F = 2r\) or \(F = 7h\)
or for \(F\) = an incorrect expression in \(r\) and \(h\))
