A rational number can be expressed as a fraction with an integer numerator and denominator. The square root of 2 is irrational, and adding 4.2 doesn't change this, since there are no integers that, when divided, form this sum.
The volume of the box is 100 cubic meter.
Step-by step explanation:
Given data:
Length of the box = 10 m
Width of the box = 5 m
Height of the box = 2 m
<u>To find the volume of the box:</u>
Volume of the box = length × width × height
= 10 m × 5 m × 2 m
= 100 cubic meter
Hence the volume of the box is 100 cubic meter.
