Rainbow [258]

Answer:

The answer to your question is the letter E. 50

Step-by-step explanation:

Data

height = ?

Width = 80 cm

Length = 40 cm

Volume = 160000 cm³

Formula

Volume of a rectangular prism = Width x length x height

Substitution

                          160000 = 80 x 40 x height

Solve for height

                           height = 160000 / 80 x 40

Simplification

                           height = 160000/ 3200

Result

                           height = 50 cm
