Answer:
1 cubic inches
Step-by-step explanation:
No of cubes = 8
Edge length of each cube = 1/2 inch
Volume of cube is given where edge is the edge length
Thus volume of cube with Edge length is calculated as explained below
Question states that there are 8 such cubes joined to make a right rectangular prism. Thus volume of right rectangular prism will be sum of volume of 8 such cubes.
volume of right rectangular prism = 8 times the volume of 1/2 inched cubes
= 8* 1/8 = 1 cubic inches
Thus volume of right rectangular prism is 1 cubic inches.
Answer:
310 inches²
Step-by-step explanation:
Given: A rectangular prism cage has a height of 28 inches.
Volume of prism is 8680 cubic inches.
We know the area of base of rectangular prism is equal to the area of rectangle.
∴ Lets find out the lenght and width of rectangular prism.
Volume of rectangular prism=
Where, w is width
l is length
h is height.
Now, putting the value in the formula of volume.
⇒
cross multiplying
⇒
∴ wl= 310 inches²
As we need to find the area of the plastic mat on the bottom of the cage, which is rectangle in shape.
Area of rectangle=
∴ Area of rectangle= 310 inches²
Hence, 310 inches² is the area of the plastic mat on the bottom of the cage.
Then just one of them takes 2h.
