entist fills a container with s0a water. The container has dimensions \( 30 \mathrm{~cm} \times 30 \mathrm{~cm} \times 40 \mathrm{~cm} \). density of sea water is \( 1020 \mathrm{~kg} / \mathrm{m}^{3} \). Calculate the mass of the sea water in the centainer.

To find the mass of the sea water in the container, we first need to calculate the volume of the container. The volume \( V \) is given by the formula: \[ V = \text{length} \times \text{width} \times \text{height} \] Converting the dimensions to meters: - Length = 30 cm = 0.30 m - Width = 30 cm = 0.30 m - Height = 40 cm = 0.40 m Now we calculate the volume: \[ V = 0.30 \, \text{m} \times 0.30 \, \text{m} \times 0.40 \, \text{m} = 0.036 \, \text{m}^3 \] Next, to find the mass \( m \) of the seawater, we can use the formula: \[ m = \text{density} \times \text{volume} \] The density of seawater given is \( 1020 \, \text{kg/m}^3 \). Now plug in the values: \[ m = 1020 \, \text{kg/m}^3 \times 0.036 \, \text{m}^3 = 36.72 \, \text{kg} \] Therefore, the mass of the sea water in the container is approximately \( 36.72 \, \text{kg} \).
