Answer:
Part A= 30 small cubes
Part B= The volume of the rectangular prism in terms of small cubes it 30 small cubes. And the unit cube is 3.75ft cubed.
Step-by-step explanation:
Part A:
30 small cubes because Length times width times height equals volume. So 1.5*1*2.5=3.75ftcubed which is the volume. Each small cubes length times width times height is 1/2*1/2*1/2 which equals 1/8ft cubed which equals volume of small cubes. To find how many fit we take the 3.75ft and divide it by 1/8 ft and you get 30. S 30 cubes fit.
Part B:
3.75 ft^3 because Length times width times height equals volume. So 1.5*1*2.5= 3.75 ft^3 which is the volume.
Hope it helps!
