The total surface area of a cube is 294cm^2 work out the volume of the cube

Answers

Good morning,

____________________

Answer:

343cm³

____________________

Step-by-step explanation:

total surface = 6r² ⇔ 294=6r²

Then, r²=294÷6=49

Then r=√(49)=7

Therefore the volume = r³=7^(3)=343cm³.

_______________________________…

:)

Answer:

total surface area=6x^2

area=x^3

6x^2=294

x^2=294/6

x^2=49

x=SQR(49)

x=7

x^3=7^3

area=343

75% of ? = 30 helppp

Answers

Answer: 40

Divide

30÷75%=40

Final Answer

40

Note: When finding answers like these divide the number by the percent.

Answer:

So 75% of 40 = 30.

Step-by-step explanation:

Hello!

Let's represent this as an equation so its easier to understand and solve.

We can represent any number as "n," and 75% as (75)/(100).

(75)/(100) · n = 30

Multiplying by 100 to get rid of the fraction:

75n = 3000

Dividing by 75:

n = 40.

So 75% of 40 = 30.

The number is \boxed{40}.

Find the value of x^3 + y^3 – 12xy + 64 when x + y = (-4)

Answers

Answer:

0

Step-by-step explanation:

Using the algebraic expansion

x³ + y³ = (x + y)³ - 3xy(x + y)

Given

x³ + y³ - 12xy + 64

= (x + y)³ - 3xy(x + y) - 12xy + 64

Substitute x + y = - 4 into the expression

= (- 4)³ - 3xy(- 4) - 12xy + 64

= - 64 + 12xy - 12xy + 64

= 0
