Volume is Length x Width x Height, so let's plug in our values to solve.
Volume = (x)(2x+3)(2x+5)
Distribute.
(2x^2+3x)(2x+5)
Distribute again.
(4x^3+10x^2+6x^2+30x)
That could be your answer, but if you'd like to simplify, you can combine like terms.
(4x^3 + 16x^2 + 30x)
Now take out GCF
2x(2x^2+8x+15)
That is your final answer.
I hope this Helps!
