(-7)^2 + 4(-7) -5
= 49 - 28 -5

The formula for finding the volume of a cube is V = a^3
Where a is the length of a side.
lets do this step by step.
First: we need to break this into to prisms.
Next lets say the dimensions:
4 x 2 x 1 and 2 x 2 x 1
now we multiply them and then add them
8 + 4 = 12
volume = 12 cubic units.
