SHUT UPPPPP HAHAHAHAHAHAHHAHAAHAAH
are these answers for connexus??????????
1. To name the figure, you need to understand the characteristics of each option given.
a) A cone is a three-dimensional figure with a circular base tapering to a point.
b) A triangular pyramid is a four-sided figure with a triangular base and three triangular faces that meet at a common vertex.
c) A triangular prism is a six-sided figure with two parallel triangular bases and three rectangular faces connecting the bases.
d) A rectangular prism is a six-sided figure with all faces being rectangles.
Based on these descriptions, the figure described in the question is a triangular prism, so the answer is c) triangular prism.
2. To calculate the surface area of a prism, you need to know the formula for surface area of a triangular prism:
Surface Area = 2(Area of triangular bases) + (Perimeter of base shape) × (Height)
Since the base shape is a triangle, the perimeter is given by the sum of the lengths of its three sides. The height of the prism is not provided in the question.
To calculate the surface area, you need the height of the prism. Without this information, it is not possible to determine the surface area. Therefore, the answer cannot be determined from the information given.
3. To calculate the volume of the sandbox, you need to know the formula for the volume of a cube:
Volume = (Side length)^3
Given that the side length of the square sandbox is 7 feet and the sand depth is 2 feet, you need to calculate the volume using the formula:
Volume = (7 ft)^2 × 2 ft
Simplifying this equation, you get:
Volume = 49 ft^2 × 2 ft
Volume = 98 ft^3
Therefore, Jamila should order 98 ft^3 of sand. The answer is a) 98 ft^3.
4. To determine the dimensions of the paper required to cover the box, you need to analyze the shape of the box shown below:
___________________
| |
| |
| |
|___________________|
Since the box has equal dimensions on all sides, we can conclude that it is a cube.
To cover the box including the ends, the dimensions of the paper should be equal to the length, width, and height of the box.
Since all sides of the box are 8 inches, the dimensions of the paper required would be 8 inches by 8 inches.
Therefore, the answer is c) 8 in x 8 in.
5. To understand what happens to the volume of a rectangular prism when each of its dimensions is doubled, we need to consider the formula for the volume of a rectangular prism:
Volume = Length × Width × Height
If each dimension is doubled, we can represent the new dimensions as 2L, 2W, and 2H, where L, W, and H are the original dimensions.
Using the new dimensions, the new volume can be calculated as:
New Volume = (2L) × (2W) × (2H) = 8(L × W × H)
Comparing the new volume to the original volume, we can see that the new volume is 8 times the original volume.
Therefore, when each dimension of a rectangular prism is doubled, the volume increases by a factor of 8. The answer is d) it is eight times as great.
I don't think you are supposed to cheat....
1. d rectangular prism
2. c 780 m2
3. a 98 ft3
4. c 8 in x 10 in
5. b it quadruples
