[tex]\textsf{FORMULAE:}[/tex]
[tex]\textsf{Volume of cube} = \text{s}^3[/tex]
[tex]\text{(x+y)}^3 = \text{x}^3 + \text{y}^3 + 3\text{x}^2\text{y} + 3\text{x}\text{y}^2[/tex]
[tex]\textsf{SOLUTION:}[/tex]
[tex]\textsf{Volume of cube} = \text{s}^3[/tex]
[tex]\textsf{Volume of cube} = \text{(x+5)}^3[/tex]
[tex]\textsf{Volume of cube} = \text{x}^3 + 5^3 + 3(\text{x})^2(5) + 3(\text{x})(5^2)[/tex]
[tex]\textsf{Volume of cube} = \boxed{\text{x}^3 + 125 + 15\text{x}^2 + 75\text{x} \: \sf inches^3}[/tex]
[tex]\textsf{ANSWER:}[/tex]
[tex]\text{x}^3 + 125 + 15\text{x}^2 + 75\text{x} \: \sf inches^3[/tex]
