Marco made of rectangular prism using 1/2 m cubes the rectangular prism has a volume of 5 m³ how many cubes did Marco use

Answers

ok so
1 find volume of 1 cube
2. find total volume of rectangular prism

1/2 m cubes
volume=side^3
side=1/2m (I guess since that was what was given)
v=1/2^3=1/8

so
volume of 1 cube times number of cubes=total volume
1/8m^3 times number of cubes=5m^3
multiply both siides by 8/1 m^3 to clea fraction (since 8/1 times 1/8=8/8=1)
number of cubes=40

What is the surface area, in square inches, of a 8-inch cube?

Answers

Answer: 384 in²

Step-by-step explanation: Surface area is the sum of the areas of all of the faces of a three-dimensional figure.

So to find the surface area of a cube, it's important to understand that each face of a cube has the same area. So we can simply find the area of one face of a cube and multiply it by the number of faces which is 6.

To find the area of one face of a cube, we can use the formula for the area of a square.

Area = S²

Since the length of a side is 8 inches, we have (8 in.)² or 8 inches x 8 inches which gives us 64 in.².

Now, since there are 6 sides to a cube, we have (64 in.)² (6) which is equal to 384 inches².

Therefore, the surface area of the cube is 384 in².

surface area of a cube=6*s^2=6*8^2=384

How do I do this?
4/5x>14

Answers


Well, first, you need to know what you want to 'do' to it.

You want to find the description of what 'x' has to be in order to
make that inequality a true statement.  Here's one way to do it:

                                              4/5 x > 14

Multiply each side by  5 :     4    x  >  70

Divide each side by  4 :             x  >  17.5 .

That's it.  As long as 'x' is more than 17.5 ,
the original inequality is true.

2)0
3)8
4)-6
Help me out guys.

Answers

Answer:

8

Step-by-step explanation:

The condition for the discriminant b² - 4ac is

If b² - 4ac > 0 then roots are real, irrational and unequal

If b² - 4ac > 0 and a perfect square, roots are real, rational and unequal.

Thus

b² - 4ac = 8

Answer:

3) 8

Step-by-step explanation:

Real and unequal:

B² - 4AC > 0

Irrational: B²-4AC not a perfect square

3/y=6/y-2
solve for y
please I need help

Answers

Answer:

The answer is y = -2.

Step-by-step explanation:

To start, you need to cross multiply to solve.

3/y = 6/(y -2)

y*6 = 3*(y -2)

6y = 3y - 6

3y = -6

y = -2
