The volume of the rectangular prism will be 10 cubic units.
let the prism with a base area of A and a height H
then the volume of the prism is given as
V = A x H
The base area is 25/4 square units and height is 8/5 units
Then the volume of the rectangular prism will be
V = 25/4 x 8/5
V = 5 x 2
V = 10 cubic units
