An illustration shows a rectangular prism made of cubes placed as 3 columns of 2 cubes high each.
Find the volume of the right rectangular prism packed with cubes. Each cube has an edge length of 13 inch. Enter the answer in a fraction and do not reduce.
The rectangular prism has a length of 2 cubes x 13 inches = 26 inches, a width of 3 cubes x 13 inches = 39 inches, and a height of 2 cubes x 13 inches = 26 inches.
The volume of the rectangular prism is length x width x height = 26 inches x 39 inches x 26 inches = 26388 cubic inches.
Since each cube has an edge length of 13 inches, the volume of one cube is 13 inches x 13 inches x 13 inches = 2197 cubic inches.
To find the number of cubes packed into the rectangular prism, we can divide the total volume of the rectangular prism by the volume of one cube:
26388 cubic inches ÷ 2197 cubic inches = 12
Therefore, the right rectangular prism packed with cubes contains 12 cubes.
The volume can be expressed as a fraction in terms of the volume of one cube:
26388 cubic inches = 12 x 2197 cubic inches
So, the volume is 12/1 times the volume of one cube, or 12/1.

An illustration shows a rectangular prism made of cubes placed as 3 columns of 2 cubes high each.
Find the volume of the right rectangular prism packed with cubes. Each cube has an edge length of 1/3 inch. Enter the answer in a fraction and do not reduce.
The rectangular prism has a length of 2 cubes x 1/3 inch = 2/3 inch, a width of 3 cubes x 1/3 inch = 1 inch, and a height of 2 cubes x 1/3 inch = 2/3 inch.
The volume of the rectangular prism is length x width x height = (2/3 inch) x (1 inch) x (2/3 inch) = 4/27 cubic inches.
Since each cube has an edge length of 1/3 inch, the volume of one cube is (1/3 inch) x (1/3 inch) x (1/3 inch) = 1/27 cubic inches.
To find the number of cubes packed into the rectangular prism, we can divide the total volume of the rectangular prism by the volume of one cube:
(4/27 cubic inches) ÷ (1/27 cubic inches) = 4
Therefore, the right rectangular prism packed with cubes contains 4 cubes.
The volume can be expressed as a fraction in terms of the volume of one cube:
4/27 cubic inches = 4/1 times the volume of one cube, or 4/1.

surface area = ____cm2
To calculate the surface area of the rectangular prism, we need to find the area of each face and then add them up.
The rectangular prism has 6 faces:
- 2 rectangular faces with a length of 17 cm and a height of 4 cm, so their total area is 2 x 17 cm x 4 cm = 136 cm^2
- 2 rectangular faces with a width of 10 cm and a height of 4 cm, so their total area is 2 x 10 cm x 4 cm = 80 cm^2
- 2 rectangular faces with a length of 17 cm and a width of 10 cm, so their total area is 2 x 17 cm x 10 cm = 340 cm^2
Adding up the areas of all 6 faces, we get:
136 cm^2 + 80 cm^2 + 340 cm^2 = 556 cm^2
Therefore, Jerry will need 556 cm^2 of wrapping paper to wrap the present.

An illustration shows a 3 D triangular prism with the triangular face as a right triangle. The edges that are not visible are represented by dashed lines. The length and base of the triangular prism measures 30.5 centimeters and 27.9 centimeters. The perpendicular side of the triangular face measures 5.1 centimeter and the hypotenuse measures 28.4 centimeter.

S.A. =___cm2
To find the surface area of the triangular prism, we need to find the area of each face and then add them up.
The triangular prism has 5 faces:
- 2 triangular faces with a base of 27.9 cm and a height of 5.1 cm, so their total area is 2 x (1/2) x 27.9 cm x 5.1 cm = 142.29 cm^2
- 3 rectangular faces with a length of 30.5 cm, a width of 5.1 cm and a height of 28.4 cm (which is the hypotenuse of the right triangle), so their total area is 3 x 30.5 cm x 5.1 cm x 28.4 cm = 43784.2 cm^2
Adding up the areas of all 5 faces, we get:
142.29 cm^2 + 43784.2 cm^2 = 43926.49 cm^2
Rounding to the nearest whole number, we get that approximately 43926 cm^2 of book cover material is needed to cover the three-ring binder.
Im sorry but I got 455cm2
I apologize for the mistake in my previous response. I double-checked my calculations and want to correct my answer.
