Question

Find the volume of a rectangular prism if the length is 3x2, the width is 2x, and the height is x2 + 3x + 5. Use the formula V = l ⋅ w ⋅ h, where l is length, w is width, and h is height, to find the volume.

5x5 + 18x4 + 30x3
5x6 + 18x4 + 30x3
6x5 + 18x4 + 30x3
6x6 + 18x4 + 30x3

Answer 2

\[V = l * w * h\]
\[V = (3x^2) * (2x) * (x^2 + 3x + 5)\]
First we can multiply the first 2 parts.
\[(3x^2)(2x) = 6x^3\]
Then we can multiply that by the last part
\[(6x^3)(x^2 + 3x + 5)\]
\[6x^5 + 18x^4 + 30x^3\]

Answer 3

So the answer would be C

Answer 4

Oh wow it's that easy
I was expecting something way out there

Answer 5

Thanks @MiniMato

Answer 6

Omg i jsut clicked the wrong one and that was the only question i missed
