John pours 96 litres of red oil into a rectangular container with length 220cm and breadth 40cm. Calculate, correct to the nearest cm, the height of the oil in the container
11cm
18cm
21cm
34cm
Correct answer is A
volume of rectangular container = L x B x H
1 litre = 1000cm3
96 litres = \(\frac{1000cm^3}{1 litres}\) x 96 litres
volume = 96000cm3
96000 = 220 x 40
96--- = 8800H
H = \(\frac{96000}{8800}\)
= 10.97cm
= 11cm
