Diego correctly points out that 108 cubes with an edge length of 1/3
inch are needed to fill a rectangular prism that is 3 inches by 1 inch by 1 1/3
inch.

Answers

Answer:

Option C) 4 cubic inches is the volume of the rectangular prism.

Step-by-step explanation:

It is given that, 108 cubes with an edge length of 1/3 inch are needed to fill a rectangular prism.

Therefore, the volume of the rectangular prism is equal to the volume of the 108 cubes needed to fill that rectangular prism.

So, we need to find out the volume of those 108 cubes in order to find the volume of the rectangular prism.

The formula for finding the volume of a cube is given by,

Volume of a cube = a³

where a represents the edge length

We know that, the edge length is 1/3 inch.

⇒ a = 1/3

Volume of a cube = (1/3)³

⇒ 1/3 × 1/3 × 1/3

⇒ 1/27 cubic inches

To find the volume of 108 cubes :

⇒ 108 × volume of one cube

⇒ 108 × 1/27

⇒ 4 cubic inches.

∴ The volume of 108 cubes is the volume of rectangular prism which is 4 cubic inches (option C)

Answer: 4 cubic inches

Answers

Beef = 11.99 x 2 1/2 = $29.975

Chicken = 6.49 x 1.8 = $11.682

in 1-3 sentences, explain how we know that the the volume of a pyramid is V=1/3Bh

Answers

Answer:

The formula for finding the volume of a pyramid is V= lwh/3. Taking this into consideration, the length times the width times the height must be one, so we put that over three.

Step-by-step explanation:

The formula for the volume of a pyramid V=1/3Bh can be derived by dividing the pyramid into three identical triangular prisms, each with height h and base area B, and then calculating the total volume of the three prisms.

What is volume?

Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.

Here,
The volume of a pyramid can be derived by considering that a pyramid is made up of a series of triangular cross-sections stacked on top of each other. The area of each triangular cross-section (the base) is given by the formula B = 1/2bh, where b is the base length and h is the height of the triangle. By multiplying the base area B by the height h of the pyramid and then dividing by 3 (to account for the triangular shape), we get the formula V = 1/3Bh for the volume of a pyramid.

The Composite figure is made up of a Triangle, and a trapezoid. What is the area of the composite figure?

Answers

Answer:

I DON'T KNOW the answer but hears the explanation.

Step-by-step explanation: So the total area of the composite shape is 30 + 20 = 50 cm². Note: An alternative method is to use the formula for the area of a trapezoid. Example 2 A circular shaped garden of radius 15m contains a square concrete region of side length 4m.

The area of the composite figure is,

⇒ 22 m²

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

The Composite figure is made up of a Triangle, and a trapezoid.

Now,

Area of triangle is;

⇒ A = 1/2 × 3 × 4

⇒ A = 6 m²

And, Area of trapezoid is,

⇒ A = (a + b) × h/2

⇒ A = (10 + 6) × 2/2

⇒ A = 16 m²

Thus, The area of the composite figure is,

⇒ 6 + 16

⇒ 22 m²
