8000 mm3


800,000 in3


8,000,000 mm3

Answer 1

The answer is option 2, 8000 mm3.

Answer 2

Option B is correct.

volume in cubic millimeters is, 8000 cubic mm

Explanation:

Volume of a cube is found by multiplying the length of any edge by itself twice.

It is given by:

`V = a^3` cubic units,......[1] where V represents the volume of a cube and a represents the side of a length.

From the given figure;

Length of a side(a) = 2 cm

Use conversion, to convert cm into mm;

1 cm = 10 mm

then;

2cm =20 mm

⇒length of a side(a) = 20 mm

Substitute the value of a = 20 mm in [1];

`V = (20)^3` cubic mm

Simplify:

`V = 8000 mm^3`

Therefore, the volume in cubic millimeters is, 8000 cubic mm
