hola lo único que tienes que hacer es multiplicar 20 por 3 espero te sirva
v = 27 cm³
m = 284 g = 0.284 kg
w = ?
Pe = ?
Formula
ρ = m/v = 284 g / 27 cm³ = 10.51 g/cm³(1 kg / 1000 g)(1000000 cm³ / 1 m³)
ρ = 10.51 kg/m³
g = 10 m/s²
w = m g = 0.284 kg (10 m/s²) = 2.84 N
Pe = ρ g = 10.51 kg/m³ x 10 m/s² = 105.1 N / m

Verified answer
v = 27 cm³
m = 284 g = 0.284 kg
w = ?
Pe = ?
Formula
ρ = m/v = 284 g / 27 cm³ = 10.51 g/cm³(1 kg / 1000 g)(1000000 cm³ / 1 m³)
ρ = 10.51 kg/m³
g = 10 m/s²
w = m g = 0.284 kg (10 m/s²) = 2.84 N
Pe = ρ g = 10.51 kg/m³ x 10 m/s² = 105.1 N / m
