To find the mass of the solid, we can use the formula:mass = density × volumeFirst, let's calculate the volume of the solid:Volume = height × width × thicknessVolume = 10 cm × 5 cm × 4 cmVolume = 200 cm³Now, we can calculate the mass:mass = density × volumemass = 18.4 g/cm³ × 200 cm³mass = 3680 gTo convert the mass from grams to kilograms, we divide by 1000:mass = 3680 g / 1000mass = 3.680 kgTherefore, the mass of the solid is 3.680 kilogram.
