Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall.
So,
Volume of Soham's video game system = 8 × 6 × 2 = 
cubic inches
As Sean's video game system measures 1 inch longer on all sides,
the video game system measures 
inches long, 
inches wide, and 
inches tall.
Volume of the video game system = 10 × 8 × 4 = 
cubic inches.
Therefore,
Combined volume of the two game systems = 
cubic inches
30 inches of ribbon because in one foot there are 12 inches so in 2 feet there are 24 inches. And 30 is greater than 24 so therefore 30 inches of ribbon is longer than 2 feet of ribbon
Well if you already know how to write an equation for a given set of proportions, then all you have to do is replace the unknown value with x, and then cross multiply and solve the equation. One important thing to remember is that for each proportion the numerator and the denominator have to be of the same units in the equation.
Answer:
Solutions for x are 2, 1/3
