it is length × width.
now the volume of a 3D-rectangle (= a rectangular prism) is simply
length × width × height.
in our case
5 1/2 × 1 1/2 × 2 = 11/2 × 3/2 × 2 = 33/2 =
= 16 1/2 cubic units

Step-by-step explanation:
X = y + 5
(x + y) = 3y - 3
y + 5 + y = 3y - 3
2y + 5 = 3y - 3
5 + 3 = 3y - 2y
8 = y
x = y + 5
x = 8 + 5
x = 13
ur numbers are : 8 and 13
