. The volume of a cube is 1728 . Find its edge and total surface area
emmasim [6.3K]

Answer:

Edge = 12

Total Surface Area = 72

Step-by-step explanation:

Volume of the cube = 1728

Length of the edge = \sqrt[3]{1728}  = 12

We know that

TSA (Total Surface Area) = 6 {a}^{2}

where a = length of edge of cube

So,

TSA of cube = 6 \times 12 = 72

Line CD passes through points C(3, -5) and D(6, 0) . what is the equation of the line CD in standard form?​
Kazeer [188]

Answer:

Option 2: 5x - 3y = 30

Step-by-step explanation:

Step 1: Find slope

(0-(-5))/(6-3) = 5/3

Step 2: Find <em>b</em>

y = 5/3x + b

0 = 5/3(6) + b

b = -10

Step 3: Write in slope-intercept form

y = 5/3x - 10

Step 4: Move x over

-5/3x + y = -10

Step 5: Multiply by -3 on both sides

5x - 3y = 30

And we have our final answer!
