Question

If each edge of a cube is doubled, (b) how many times will its volume increase?​

Answer 1

Answer:

The volume of the cube increases by eight times.

Step-by-step explanation:

⇒(i) Initial surface area =6×l×l

New surface area =6×(2×l)×(2×l)=4× initial surface area.

So, the new surface area will be increased by 4 times.

⇒(ii) Intial volume =l×l×l

Final volume =(2l)×(2l)×(2l)=8× initial volume.

So, volume of the cube will be increased by 8 times.
