Answer :
18 = 2·3·3
So possibles prisms are:
2×3×3
1×2×9
1×6×3
1×1×18
Therefore Quentin can make 4 different rectangular prism with 18 unit cubes.

Answer:
Quentin could built 3 different rectangular prism.
Step-by-step explanation:
Quentin could built by arranging the unit cubes in rows and columns. Let us say R units cubes are in a row and C unit cubes in a column.
R × C = 18 = 1 × 2 × 3 × 6 × 9 × 18
1. R = 18 C = 1 This prism is same as if R = 1 and C = 18
2. R = 9 C = 2 same if R = 2, C = 9
3. R = 3 C = 6
So answer is 3.
