what is the answer for this?

Answer:
0.729 cubic millimeters
Step-by-step explanation:
Here,
Length ( l ) = 0.9 mm
Base ( b ) = 0.9 mm
Height ( h ) = 0.9 mm
l = b = h = 0.9 mm = a
To find : Volume
This shape is a cube.
Formula : -
Volume of cube = a³
Volume of cube
= 0.9³
= 0.9 x 0.9 x 0.9
= 0.729 cubic milimeters
Answer:
Formula for volume of cube;
V = [tex]s^{3}[/tex]
Where 's' represents one side of a cube which is being cubed.
or
V = w · l · h
Where 'w' stands for the width, 'l' is the length, and 'h' represents the height.
For this, I'll be using the formula [tex]s^{3}[/tex].
What we know:
Use one of these sides to substitute for 's';
V = [tex]s^{3}[/tex]
V = 0.9^3 ← (The " ^ " symbol is another way of showing to the power of.)
V = (0.9 · 0.9 · 0.9)
V = 0.729 mm, the volume of this cube is 0.729 cubic millimetres.
