Question

If each edge of a cube isDecreased by 30 % then find the corresponding decrease in volume​

Answer 1

Answer:

34.3%

Step-by-step explanation:

considering the age of cube at 10 unit

then volume of cube is

10 x 10 x 10 =1000 unit ³

on reducing the edge of cube by 30% the edge will become 7 unit

then the new volume will be come

7³ = 343 unit ³

the decrease in volume in percentage can be found out as

(100 x 343)/1000

=34.3%
