Answer:

V= LWH

= (2x + 3) (x - 4) (5x + 2)

= 10x³ - 21x² - 70x - 24

Answer:

V = L × W × H

Step-by-step explanation:

The shape of the box is of a rectangular prism.

Rectangular prisms have three dimensions, namely the length (L), width (W), and height (H). To get its volume, we just have to multiply these dimensions by themselves and we will get the volume of the rectunglar box already (L × W × H).
