What is the volume of this cube?

A. 4
B.3
C.6
D.1​

Step-by-step explanation:

Length of cube (L) = 1 ft

Volume of the cube

= L³

= 1³

= 1 ft³

Hope it will help :)❤

D) 1

Step-by-step explanation:

D)1

to find the area follow the formula length * width * height

l * w * h

substitute the numbers

1 * 1 * 1

= 1

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
