Answer:
6 cm
Step-by-step explanation:
Given :-
three cubes having 3,4and5 cm sides
find out :-
side of cube formed by using these three cubes
Solution :-
as we know that volume of a cube is = A³ (where a is side of cube)
So volume of all the cubes is
=> 3³ + 4³ + 5³
=> 27 + 64 + 125
=> 216 cm³
it means the biggest cube which is formed using the three cubes has volume of 216 cm³
now
=> A³ = 216
=> 6³ = 216
means cube's side is 6cm
