10.5 + 3 X 2 - 6 = 10.5
steps: 3X2 = 6
10.5 + 6 = 16.5
16.5- 6 = 10.5
let me know if i did something wrong
I assume we are solving for x see attachment.
The side length is 3 inches
<h3>What is the perimeter of a cube?</h3>
The formula for perimeter of a cube is given as:
Perimeter = 12 × side length
We have that;
- Perimeter = 36 inches
- Side length be x
Substitute into the formula
12x = 36
Divide both sides by 12
12x/12 = 36 / 12
x = 3 inches
The side length is x and equal to 3 inches.
Hence, the side length is 3 inches
