Sandy is correct.

The correct options are;

1) Sandy is correct

2) The figure was divided into two rectangular prisms that are calculated separately

Step-by-step explanation:

Here we have to divide the figure into two rectangular prisms so as not to calculate for a dimension twice

Therefore, the figure can be split into a horizontal prism at the top with dimensions and volume = 10 * 4 * 3 and the vertical prism below will now have a dimension and hence, volume of 4 * 4 * 3

Therefore the volume of the figure is the sum of the volumes of the two prisms found as follows;

Volume of the figure = 10 * 4 * 3 + 4 * 4 * 3 = 168

We can try the othe way to confirm as follows

Volume of the prism below = 4 * 3 * 8 = 96

Volume of the horizontal prism above is now = 4 * 3 * 6 = 72

Volumre of the figure = 96 + 72 = 168

Therefore, since the volume = (10 * 4 * 3) + (4 * 4 * 3), Sandy is correct

Because the figure was divided into two rectangular prisms that are calculated separately.
