Determination of volume Using a Mathematical Formula

1. The volume of a solid with a geometric shape can be calculated using mathematical formulas.

2. Use the following formulas to calculate the volume of a solid.

a. Volume of a cube or rectangle:

volume (cm³) = width (cm) x length (cm) x height (cm)

b. Volume of a sphere:

volume (cm³) = 4.2 x radius (cm) x radius (cm) x radius (cm)

c. Volume of a cylinder:

volume (cm³) = 3.14 x radius (cm) x radius (cm) x height (cm)
