Answer:
Find the edge:
Volume = edge³
edge³ = 0.125
edge = ∛0.125
edge = 0.5 cm
If the edge is increased 3 times
⇒ edge = edge x 3 = 0.5 x 3 = 1.5 cm
Find the volume:
Volume = edge³
Volume = 1.5³
Volume = 3.375 cm
Find the number of times it increased:
30375 ÷ 0.125 = 27 times
Answer: The edge is 0.5 cm. The volume is increased 27 times when the length is increased 3 times.

Answer: The edge is 0.5 cm. The volume is increased 27 times when the length is increased 3 times.
By finding the cube root- length of its edge =0.5 2. If the length of edge of cube is tripled, its volume increases by 27 as s^3= volume of a cube so (3x)^3= 3x × 3x × 3x= 27x
