What is the width of the cuboid?
To solve the problem, let's recall the formula for calculating the surface area of a box:
(width*length + height*width + height*length) *2
Let's substitute the known values into the formula, and we'll denote the missing side as X:
2*(3*7+7*X+3*X) = 122
2*(21+7x+3x) = 122
2(21+10x) = 122
Let's expand the parentheses:
42+20x=122
Let's move terms:
20x=122-42
20x=80
Let's simplify:
x=4
And that's the solution!
