Question

A cube made out of wood has a mass of 1.2 kg and the density of the wood is 400kg/m3.What is the length of the side of the cube?​

Answer 1

≈ 0.144 m

Step-by-step explanation:

Density is mass divided by volume:

D = M / V

Solving for volume:

V = M / D

Given M = 1.2 kg and D = 400 kg/m³:

V = 1.2 kg / (400 kg/m³)

V = 0.003 m³

Volume of a cube is the side length cubed:

V = s³

Therefore:

s³ = 0.003 m³

s ≈ 0.144 m

Round as needed.
