Answer:
27/64 cubic inches.
Step-by-step
Given: Edge length of cube = 3/4 inch
To find: Volume of the rectangular prism
Solution:
A cube is a three-dimensional solid object which has 12 edges, 8 vertices and 6 faces.
A rectangular prism is a solid three-dimensional object which has six faces that are rectangles.
Let n denotes number of cubes inside the rectangular prism
Volume of one cube = edge)3= 3/4 3 cubic inches
So, volume of rectangular prism =volume of n cubes = 27/64 n
