The volume of a cube is given by the formula:


V=s^3

Where

s is the side length of a cube

Combined Volume of two cubes

Now, let's find the combined volume of the cubes with side lengths shown:


\begin{gathered} V=4^3+6^3 \\ V=64+216 \\ V=280 \end{gathered}

Volume of larger cube

Plugging into the formula, we get:


\begin{gathered} V=s^3 \\ V=10^3 \\ V=1000 \end{gathered}

Thus, we clearly see that:


280\\eq1000

Thus,

Ben isn't correct
