. 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

Maru [420]

Answer:

Maria (I THINK)

Step-by-step explanation:

Tanya is running 70 yards in all, while maria would be running more based on the pythagorean theorem

The pythagorean theorem is that on a right triangle, the square root of the two legs equal the hypotenuse

40^2+ 70^2 =c^2

6500=c^2

square root both sides

and roughly c= 80.6 yards so maria runs more

(Im not sure it is a right angle though?)
