Determine the density of a piece of laundry soap, the mass of which is 350 g, the length is 9 cm

Determine the density of a piece of laundry soap, the mass of which is 350 g, the length is 9 cm, the width is 7 cm, and the height is 5 cm.

Problem data: m (mass of a piece of laundry soap) = 350 g (in SI m = 0.35 kg); L (piece length) = 9 cm (in SI L = 0.09 m); b (width) = 7 cm (in SI b = 0.07 m); h (height) = 5 cm (in SI h = 0.05 m).

We calculate the density of a piece of laundry soap by the formula: ρх.m. = m / V = m / (L * b * h).

Let’s make a calculation: ρх.m. = 0.35 / (0.09 * 0.07 * 0.05) = 1111.1 kg / m3.

Answer: A bar of laundry soap has a density of 1111.1 kg / m3.
