A. is 21.98 cm
b. is 22 cm
Okay, so 2/3 minus 2/3 would equal to 0. hope this helps :)
Answer:

Step-by-step explanation:
A rectangular prism is a polyhedron with six rectangular faces. The volume of a prism is given by:
Volume = width * height * length
From the diagram, the rectangular prism is made up of cubes. Each cube is has a size of 1/3 ft by 1/3 ft.
The height of the prism is made up of 5 cubes. Height = 5 * 1/3 = 5/3 ft.
The length of the prism is made up of 3 cubes. length = 3 * 1/3 = 1 ft.
The width of the prism is made up of 2 cubes. Width = 2 * 1/3 = 2/3 ft.
The volume of the prism = width * height * length = 2/3 * 5/3 * 1 = 10/9 ft³ = 
47/5=9.40
9*5=45
47/5= 9 2/5
Answer:
576 cubic ft
Step-by-step explanation:
Volume of prism is = area of base of prism * height
given prism is rectangular with length of 8 feet and width of 6 ft
area of rectangle is = length * width
for the given prism area of base = 8 * 6 = 48 square ft
height of prism = 12ft
therefore volume of prism = area of base of prism * height
= 48 square ft *12 ft = 576 cubic ft
