Answer:
Volume of a cube with side length 1/3 of a meter = 1/27m^3
Step-by-step explanation:
Let
1 meter = m
V = s^3
Where,
V= volume of a cube
s= side length
s = 1/3 of a meter
= 1/3 × m
= 1/3m
V = s^3
= 1/3^3
= 1/3m * 1/3m * 1/3m
V = 1/27m^3
Volume of a cube with side length 1/3 of a meter = 1/27m^3
