Question

A cubical tank of edge 10m is filled with water up to a height of 5m, how many small
cubes of edge 25 cm is dropped in the tank so that 10% of the tank capacity water overflow.
​

Answer 1

Step-by-step explanation:

Correct option is A 800

We know, volume of a cube v=a³, where a is the edge of the cube.

Given, Edge of the tank a=2m.

Then, volume of the tank =2³ =8m³.

Since, 1m³ =1000l,

volume of the tank =8×1000L=8000L.

Also, the capacity/volume of the bucket =10L.

Then,

Number of buckets that can be filled=

Volume of tank

——————————

Volume of bucket.

= 8000

–—————— =800 buckets.

10

So, here is your answer;. I hope it helps you!!!!!!!
