The large solid below is made from small cubes. Each has a side length of 1/4.
Answer the questions below. Write your answers in simplest form.
(c) What is the volume of the large solid?

Answers

Answer:

A is 36 small cubes, because by looking at the image, you can see 3 rows of cubes containing 6 cubes each. So that would be 3 times 6, which is 18. There are 2 of these arrangements, one on top and the other on the bottom. So we multiply 18 by 2 to get 36 small cubes.

B is 1/64ft cubed, because the volume of a cube is length x width x height, and because each is the same (it is a cube) we take the length of the cube (1/8) and multiply it 2 times, to get 1/8 x 1/8 x 1/8 = 1/64 cubic feet.

C is 9/16 cubic feet for the volume of the entire cube. Because we know that there are 36 small cubes total, and we know that each cube is 1/64 cubic foot in volume, we multiply 36 small cubes, by their volume, 1/64 feet cubed to get the fraction of 9/16 .

Step-by-step explanation:

Answer:

3/4 x 6/4 x 2/4

Step-by-step explanation:

You need to multiply length * width * height to find volume.

Since each cube is 1/4, we have to multiply 3 for the width.

3 x 1/4 = 3/4.

Since there are 6 cubes for the length, you have to multiply 6 x 1/4 = 6/4

Finally, since the height is 2 cubes, you have to do 2 x 1/4 = 2/4

Finally, you multiply them all.

3/4 x 6/4 x 2/4

How do you identify the constant of proportionality when given an equation?

Answers

The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

Answer: 101 Degrees for angle BCD

Step-by-step explanation: All 3 angles in any triangle add up to 180, in the first triangle (one on the left), you have 58 and 78 degrees, add them both and subtract from 180, you get 44 degrees for angle C on the left. Do the same on the right side of the triangle, you should get 35 degrees for angle C on the right. Add them both up, (35+44) then subtract from 180 degrees to find the measure of angle BCD.
