• A. Unit = centimeter, 50 times
• B. Unit = meter, 50 times
• C. Unit = litre, 50 times
• D. Unit = Kilogram, 50 times

Answer 1

The correct option is A Unit = centimeter, 50 times

A concrete number is a number which refers to a particular unit and is meaningful. For example: 5 Kilogram, 2.5 Litre, 8 Metre.

Here, 50 cm represents the breath of the cuboid, which is 50 times of the centimeter.
