The volume of the rectangular prism is 1/10 cubic units
<h3>Volume of a rectangular prism</h3>
The formula for calculating the volume of a rectangular prism is expressed as;
V = Bh
B is the base area
h is the height
Given the following parameters
B = 3/20 units²
h = 2/3 units
Substitute
V = 3/20 * 2/3
V = 2/20
V = 1/10 cubic units
Hence the volume of the rectangular prism is V = 1/10 cubic units

Since the two numbers vary directly, if Y is quadrupled, X will do the same. 2 times 4 is 8, 15 times 4 is 60.
X = 60.
