Answer 1

1. The rectangular solid has a length, width and height.

volume = length x width x height.

2. The volume is the multiplication of these 3 measurements.

Volume = 2.31 x 2.32 x 8.45 = 45.3 cm^3

3. Density is mass of a substance per unit volume.

Density = mass/volume

4. volume = length x width x thickness

thickness = volume/(length x width)
