Question

I really need help!!!!!! 25 points!!

1.) What is the area of a square with side lengths of 3/5 units?

2.) What is the side length of a square with area 1/16 square units?

3.) What is the volume of a cube with edge lengths of 2/3 units?

4.) What is the edge length of a cube with volume 27/64 cubic units?

You don’t have to answer all but could you please explain a bit when you give an answer?? I really need the help.

Answer 1

1. 9/25 units^2

2. s = 1/4 unit

3. = 8/27 units^3

4. s = 3/4 unit

Explanation:

1. The area of a square is A=s^2

A = (3/5)^2

= (3/5) *(3/5)

= 9/25 units^2

2. The area of a square is A=s^2

1/16 = s^2

Take the square root of each side

sqrt(1/16) = sqrt(s^2)

1/4 = s

s = 1/4 unit

3. The volume of a cube is V = s^3

V = (2/3)^3

= (2/3) (2/3) (2/3)

= 8/27 units^3

4.The volume of a cube is V = s^3

27/64 = s^3

Take the cube root of each side

(27/64)^(1/3) = (s^3)^(1/3)

3/4 = s

s = 3/4 unit
