How much weights a glass cube (p = 2.5 g / cm3), if the length of the cube is l = 40 mm?

How much weights a glass cube (p = 2.5 g / cm³), if the length of the cube is l = 40 mm?

ρ = 2.5 g / cm 3

l = 40 mm

m =?



Solution


m =?

m = ρ x 1³

m = 2.5 g / cm³ x (40 mm)³

m = 2.5 g / cm³ x (4 cm)³

m = 2.5 g / cm³ x 64 cm³

m = 160 g



Legend
m = mass (g)
l = length (mm)
ρ = density (g / cm³)
glass density = ρ = 2.5 g / cm³
