What is the side length of a wooden cube if we know its mass m = 62.5 grams?

We know

ρ = 500 kg / m³
(density of wood)

m = 62.5 g

l =?



Solution

we use density formula:

ρ = m / V

V = 13

V = m / ρ

l³ = 62.5 g / 500 kg / m³

l³  = 62.5 g / 0.500 g / cm³

l³  = 125 cm³

l³  = (5 cm)³

l = 5 cm
