A solid is 10 cm tall, 5 cm wide and 4 cm thick. It has a density of 18.4g/cm^3 What is its mass , in kilogram? 2.980 kilogram 3.940 kilogram 2.770 kilogram 3.680 kilogram

To find the mass of the solid, we can use the formula:<br /><br />mass = density × volume<br /><br />First, let's calculate the volume of the solid:<br />Volume = height × width × thickness<br />Volume = 10 cm × 5 cm × 4 cm<br />Volume = 200 cm³<br /><br />Now, we can calculate the mass:<br />mass = density × volume<br />mass = 18.4 g/cm³ × 200 cm³<br />mass = 3680 g<br /><br />To convert the mass from grams to kilograms, we divide by 1000:<br />mass = 3680 g / 1000<br />mass = 3.680 kg<br /><br />Therefore, the mass of the solid is 3.680 kilogram.
