The rainwater

The rainwater container has the shape of a block whose bottom has dimensions of 4.5 m and 3.5 m. It is partly filled with water. What is the level if there is 189 hl of water in it?

Correct answer:

h =  1.2 m

Step-by-step explanation:

a=4.5 m b=3.5 m V=189 hl m3=189/10  m3=18.9 m3  S=a b=4.5 3.5=634=15.75 m2 h=V/S=18.9/15.75=65=65 m=1.2 m



We will be pleased if You send us any improvements to this math problem. Thank you!
