Answer:
The side length is 3 cm
Step-by-step explanation:
The formula for volume of a cube is given by
V = s^3 where s is the side length
27 cm^3 = s^3
Take the cube root of each side
(27 cm^3 ) ^ (1/3) = (s^3)^(1/3)
3 cm = s
The side length is 3 cm
Answer:
15
Step-by-step explanation:
Given: y is directly proportional to when x = 7, y = 9
To find: y when x = 23
Solution:
u and v are said to be proportional if where k is a constant of proportionality.
As y is directly proportional to when x = 7, y = 9,
Put x = 7, y = 9
Put x = 23
