The lengths of the sides of a small cube are 1 over 4 foot each.

Part A: How many small cubes can be packed in the rectangular prism? Show your work. (5 points)

Part B: Use the answer obtained in part A to find the volume of the rectangular prism in terms of the small cube and a unit cube. (10 points)

Answers

Answer: 84 cubes

Step-by-step explanation: Given, The dimension of the rectangular prism are, 1 1/3 ft. * 1 * 2 1/3 = 4/3 * 7/3 = 28/9 cube ft.

Now, the volume of a cube = side³, if side = 1/3 ft., Then the volume of each cube, V = (1/3)³ = 1/27 cube ft.

Hence, the number of cubes that can be packet in the prism = V/V1 = 28/9 / 1/27 = 27*28/9 = 3 * 28 = 84

A) The number of small cubes which can be packed in the rectangular prism are 180.

B) The volume of the rectangular prism in terms of the small cube and a unit cube will be 180 units³

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

Length = 2 1/4 feet

Width = 1 feet

Height = 1 1/4 feet

And, The lengths of the sides of a small cube are 1 /4 foot each.

Now,

Since, The volume of rectangular prism = Length x width x height

Substitute all the values, we get;

⇒ The volume of rectangular prism = 2 1/4 × 1 × 1 1/4

                                                       = 9/4 × 1 × 5/4

                                                       = 45/16 ft³

                                                       = 2.81 ft³

And, The Volume of one cube = Side³

Here, The length of side of cube = 1/4 feet = 0.25 feet

Hence, The Volume of one cube = Side³

The Volume of one cube = 0.25³

The Volume of one cube = 0.015625 ft³

So, The number of small cubes that can be packed in the rectangular prism = Volume of rectangular prism / Volume of cube

         = 2.81 /0.015625

         = 180

B) The length, the width and the height of the rectangular prism in term of units cubes is:

Length = 2 1/4 feet / 0.25 feet = 2.25 / 0.25 = 9 units

Width = 1 feet / 0.25 feet = 4 units

Height = 1 1/4 feet / 0.25 feet = 1.25 / 0.25 = 5 units

So, The volume of the rectangular prism in terms of the small cube and a unit cube is,

Volume = 9 x 4 x 5

            = 180 units³

Jabari had two equations to solve. Both had two unknowns, x and y. Jabari could use them to solve each other. That's called (_______). Jabari decided to (_______) using the substitution method. First, he had to turn the x's in one equation into y's. He subtracted 2y from both sides of the first equation x+2y = 4. This made x = 4−2y.
Next, he substituted the expression 4−2y for x in (_______). Now he had (4-2y)−2y = 6.
Jabari saw that the two 2y's were like terms. He knew that collecting like terms is a way to (_______). He combined the y's to get 4−4y = 6.
From there, he subtracted 4 from both sides to get −4y=2. Now it was easy to evaluate the expression down to a single value. The problem's solution was (_______).
