Answer 1

The answer to your question is the letter A. 9 and 10 units

Explanation:

Data

Volume = 800 u³

length of an edge = ?

Process

1.- Look for the formula of Volume of a Cube

Volume = side³

2.- Calculate the length of a side

800 = side³

-Simplification

side = ∛800

-Result

side = 9.28

3.- Compare the result with the choices

The right answer is letter A because 9.28 is higher than 9 and lower than 10 units.
