Explain how to find the volume of a cube that has edge length 1/4 yd. Then, find the volume of the cube.
Answer in complete sentences, include all relevant formulas and calculations, and be sure to include appropriate units.

Answers

Answer:

1/64 cubic yards or 0.015625 cubic yards

Step-by-step explanation:

A cube has equal edge lengths.

To find the volume of a cube using edge length, simplify raise the value of the edge length to the 3rd power or cube it.

⇒ V = (edge length)³

Using this formula and keeping in mind the edge length is 1/4 yd, substitute it in the formula.

V = (1/4)³V = 1/64 [4³ = 64]V = 1/64 cubic yards or 0.015625 cubic yards

Answer:

Volume of the cube is 1/64 yd³.

Step-by-step explanation:

Given that, Length of each edge of the cube is 1/4 yard.

Using formula:

[tex] \: \: \dashrightarrow \: \: { \underline{ \boxed{ \pmb { \sf{ \purple{Volume _{(cube)} = (edge) ^{3} }}}}}} \\ [/tex]

On substituting the value of edge in the above formula, we will get the required volume of the cube.

[tex] \: \: \dashrightarrow \: \: \rm Volume = \bigg( \dfrac{1}{4} \bigg) ^{3} \\ [/tex]

[tex]\: \: \dashrightarrow \: \: \rm Volume = \dfrac{1}{4} \times \dfrac{1}{4} \times \dfrac{1}{4} \\ [/tex]

[tex]\: \: \dashrightarrow \: \: { \underline{\boxed{ \purple{\pmb{ \sf {Volume = \dfrac{1}{64} \: {yd}^{3} }}}}}} \\ \\ [/tex]

Hence,

Volume of the cube is 1/64 yd³

Each figure below is made up of congruent
trapezoids. Find the area of the figure.

Answers

Answer:

12 [tex]c[/tex][tex]m^2[/tex]

Step-by-step explanation:

The formula to find the area of a trapezoid is A = h. We replace the "a" and "b" with 6cm. We then replace the "h" with 12cm as your height is 12cm. The new formula is A = h = x 12. The answer to that equation is 12cm.

The table above shows the total number of pictures Cal took by the end of each week. Based on this pattern, which expression can be used to find the total number of pictures Cal took by the end of w weeks?

options:

2 x w

4 x w

w + 12

4 x w + 4

Answers

So the slope is (y2-y1)/(x2-x1)

(8-4)/(2-1)=
4/1 =
4

Aka. For every 1 week, the number of pictures taken increases by 4.

So it is 4 * w

Check:
4*w = total number of pictures
4*1 = 4
4*2 = 8
4*3 = 12
4*4 = 16

All match the table.

D) The median of 2nd Period is greater then the median of 1st Period.

Answers

It’s D) The median of 2nd period is greater then the median of 1st period

The correct statement is,

''The median of 2nd Period is greater than the median of 1st Period.''

We have to given that;

Mr. Kugler gave the same geometry test to his 1st and 2nd period classes.

And, The box and whisker plot summarizes the scores of each class.

Now, From figure;

The median of 2nd Period is,

⇒ 85

And, The median of 1st Period is,

⇒ 80

Thus, 80 < 85

Hence, The correct statement is,

''The median of 2nd Period is greater than the median of 1st Period.''
