A piece of black onyx was cut into a rectangular solid measuring 5.10 cm by 5.10 cm by 2.50 mm . What is the volume in cubic centimeters?

Explanation:

Given

Initial Form: Onyx

Final Form: Rectangular Solid

Dimension of Solid = 5.10 cm by 5.10 cm by 2.50 mm

Required

Volume of the solid (in cm³)

The volume of a solid is calculated as thus;

Assume the following;

The first thing to do is to convert the assumed height from mm to cm

Given that;

This implies that

Hence, the dimension of the solid in cm is:

The Volume is then calculated as;

Hence, the volume of the rectangular solid is
