A block of wood is 10 m long, 63 cm wide, and 100 mm high. Can you find the block's mass when the density is 443 kg/m^3 ?

Answer 1

Step 1 - Find the volume of the block. Since the density is represented in kg/m^3, we will make sure to find the mass in m^3.

1. We need to convert 63 cm to m. Since there are 100 cm in a m, we will need to divide 63 cm by 100. This results in 0.63 m wide.
2. We need to convert 100 mm to m. Since there are 1000 mm in a m, we will need to divide 100 mm by 1000. This results in 0.1 m high.
3. We will multiply the length, width, and height to get the volume. This is 10 m * 0.63 m * 0.1 m = 0.63 m^3.

Step 2 - Find the mass by dividing the volume by the density. This is 0.63 m^3 / 443 kg/m^3. The m^3 cancel out and gives a final answer of 0.0014 kg
