A wooden block of dimensions 3 cm × 3 cm × 4 cm floats vertically in methylated spirit with 4 cm of its length in the spirit. Calculate the weight of the block. (Density of methylated spirit = 8.0 × 10² kgm^-3)

---

Volume of the spirit displaced = (3 × 3 × 4) = 36 cm³ = 3.6 × 10^-5 m³
Weight of the block =v_d × p × g = (3.6 × 10^-5) × 8.0 × 10² × 10 = 2.88 × 10^-1N.
