Q. |
The length, breadth, and height of a cuboid increase by 20%, 10%, and 10% respectively. By how much% will the volume increase? |
|
A. 42% |
|
|
B. 45.2% |
|
|
C. 42.5% |
|
|
D. 60% |
Volume = l × b × h
There are 3 dimension, we need to apply AB method twice
20 + 10 + 20*10/100 = 32
32 + 10 + 32*10/100 = 45.2%
Hence the volume will increase by 45.2%
