A container will hold exactly 550 litres. It is measured to 80 cm by 75 cm and 90 cm, to the nearest cm. How does this affect its capacity?
The capacity is definitely more than 550L
The capacity could be less than 550L
The container is very likely to hold 550L
The container will never hold 550L
Explanation
The lower bound is 79.5 x 74.5 x 89.5= 529672.125. This is far less than the 550L
