To find the area of a rectangular prism multiply length by width by height.
If the problem has a variable take the two other dimensions and multiply them together. Then take that number and subtract it from the total to find the number that the variable equals.
The answer is 30
You multiply 2 x 30 which is 60 and 60 + 30 = 90
hope this helps :D
