Question

A cube has a volume of (0.75xy)3 cubic centimeters.
What is the volume of the cube expressed as a fraction?

Answer 1

Answer:

$\frac{27}{64} x^{3} y^{3} cm^{3}$

Step-by-step explanation:

0.75 means  75/100 which is equal to 3/4.

Cube of 3/4 is $\frac{3^{3} }{4^{3} }$= 27/64

x cube means x will be multiplied with itself thrice, which is $x^{3}$and following the same logic, y cube means y will be multiplied with itself three times which is $y^{3}$. The unit $cm^{3}$at the last is very important, because, without it, the value does not show that this value is used to represent a volume so we write the units after writing the value.
