Question

A box is x inches high, (2x + 3) inches wide, and (2x + 5) inches long. In terms of x, what is the volume (V) of the box?

Answer 1

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!

Answer 2

 I think it's 4x + 8 I'm not really sure
