Answer:
6*W^3 cubic units
Explanation:
Right rectangular prism volume (V) is calculated as
V = L*W*H
where L is length, W is width and H is height
The height is three times the width of the base means
H = 3*W
The length of the base is twice the width means
L = 2*W
Replacing in volume formula
V = 2*W*W*3W
V = 6*W^3
