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?

Respuesta :

Answer:

[tex]Volume = 6.5025cm^3[/tex]

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;

[tex]Volume = Length * Width * Height[/tex]

Assume the following;

[tex]Length = 5.10cm\\Width = 5.10cm\\Height = 2.50mm[/tex]

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

Given that;

[tex]1mm = 0.1cm[/tex]

This implies that

[tex]2.50mm = 2.50 * 0.1cm\\2.50mm = 0.25cm[/tex]

Hence, the dimension of the solid in cm is:

[tex]Length = 5.10cm\\Width = 5.10cm\\Height = 0.25cm[/tex]

The Volume is then calculated as;

[tex]Volume = 5.10cm* 5.10cm * 0.25cm[/tex]

[tex]Volume = 6.5025cm^3[/tex]

Hence, the volume of the rectangular solid is [tex]Volume = 6.5025cm^3[/tex]
