Why is volume represented with cubic units?
dolphi86 [110]

Answer:

Volume is measured in "cubic" units. The volume of a figure is the number of cubes required to fill it completely, like blocks in a box. Volume of a cube = side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed.

-7x- 8y=9<br>4x +9y=-22​
BlackZzzverrR [31]

Answer:

(95/31, -118/31)

Step-by-step explanation:

-7x-8y=9

4x+9y=-22

----------------

4(-7x-8y)=4(9)

7(4x+9y)=7(-22)

-----------------------

-28x-32y=36

28x+63y=-154

-----------------------

31y=-118

y=-118/31

-7x-8(-118/31)=9

-7x+944/31=9

-7x=9-944/31

-7x=279/31-944/31

-7x=-665/31

7x=665/31

x=(665/31)/7

x=(665/31)(1/7)

x=665/217=95/31

x=95/31, y=-118/31

The solid surface area is equal to the solid volume. Find the value of x? The measurements of the rectangular prism is 9 inches
Fudgin [204]

Answer:

x=7.2

Step-by-step explanation:

Let x represent height of the prism.

We know that volume of rectangular is equal to product of its height, width and length.

\text{Surface area of rectangular prism}=2(wl+lh+hw), where w, h and l represents width, length and height respectively.

We have been given that the surface area of rectangular prism is equal to the volume of the prism. So we can set an equation as:

lwh=2(wl+lh+hw)

We are also told that the measurements of the rectangular prism is 9 inches long and 4 inches wide. Upon substituting these values in above equation, we will get:

9\cdot 4\cdot x=2(4\cdot  9+9\cdot x+x\cdot 4)

Let us solve for x.

36x=2(36+9x+4x)  

36x=2(36+13x)

36x=2(36+13x)

36x=72+26x

36x-26x=72+26x-26x

10x=72

x=\frac{72}{10}\\\\x=7.2

Therefore, the value of x is 7.2 inches.
