Question

v = 7 + 3x
if there were 8 cubes in the container,
the volume would be \\(\boxed{}\\) ml.

Explanation:

Step1: Identify the value of x

Here, the number of cubes is \( x \), and \( x = 8 \).

Step2: Substitute x into the formula

The formula for volume is \( v = 7 + 3x \). Substitute \( x = 8 \) into the formula:
\( v = 7 + 3\times8 \)

Step3: Calculate the result

First, calculate \( 3\times8 = 24 \), then \( 7 + 24 = 31 \).

Answer:

31
