Answer:
3.375
Explanation:
To get the volume of a cube you need to multiply length width and height since the cube is similar in length width and height you need to multiply 1.5 by itself three times.
V=l×w×h
V=1.5×1.5×1.5
V=3.375
Note:you need to multiply it to itself three times not to the number three.
Also it is only used if one number is given if three numbers are given multiply those three numbers hope this helps have a good day
