Answer 2

Problem Analysis

We are given that there are 8 red cubes in a box, and the number of green cubes is 2 more than the number of red cubes. We need to determine the total number of red and green cubes in the box.

Solution

Let's denote the number of red cubes as R and the number of green cubes as G.

From the given information, we know that: - R = 8 (there are 8 red cubes in the box) - G = R + 2 (the number of green cubes is 2 more than the number of red cubes)

To find the total number of red and green cubes in the box, we can substitute the value of R in the second equation: G = 8 + 2

Simplifying the equation, we get: G = 10

Therefore, there are 10 green cubes in the box.

To find the total number of red and green cubes, we can add the number of red and green cubes together: Total = R + G = 8 + 10 = 18

Therefore, there are 18 cubes in total in the box.

Answer

There are 8 red cubes and 10 green cubes in the box, making a total of 18 cubes.
