Answer:
A rational number.
Step-by-step explanation
A rational number is a ratio of whole numbers.
1/3 is the ratio of 1:3
3:1 becomes 3/1 = 3
32:10 can be written 32/10 or 16/5 or 3.2
16/5 is a rational number 16 and 5 are integers, 5 is not equal to 0.
Therefore, 3.2 which can be expressed as 16/5 is a rational number.
Volume of water
=6600 l=6600×0.001m³=6.6m³
▶Considering only inner volume
Let,
x↪ thickness of bottom of cuboid
Then,
↪h=3.5-x
{to get inner height of cuboid}
↪ b=1.2m-2×10cm=1.2m-0.2m=1m
{to get inner breadth of cuboid we must subtract it from 2×thickness of wall }
↪ l=2.4m-2×10cm=2.4m-0.2m=2.2m
{to get inner length of cuboid we must subtract it from 2×thickness of wall }
❇Since
↪inner volume=volume of water
↪ l×b×h=6.6
↪ 2.2×1×(3.5-x)=6.6
↪ 3.5-x=6.6/2.2
↪ x=3.5-3
↪ x=0.5m➡required thickness
Answer:253/4 or 63.25
