. 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 = $6 \times 12 = 72$

Multistep: At 7 p.M. Last night, the temperature was 10 degrees Fahrenheit. At 7 a.M. The next morning, the temperature was -2 d

larisa86 [58]

Answer:

The temperature changed by $-12^\circ F$ overnight.

The temperature changed by $-1^\circ F$ overnight each hour.

Step-by-step explanation:

Given that:

Temperature at 7 PM last night = $10^\circ F$

Temperature at 7 AM the next morning = $-2^\circ F$

a. The change in temperature from 7 PM to 8 AM = Temperature at 7 AM - Temperature at 7 PM

$\Rightarrow -2-10 =\bold{-12^\circ F}$

Negative sign indicates that the temperature has decreased.

b. Change in temperature each hour:

Divide the Change in temperature with the number of hours.

$\Rightarrow \dfrac{-12}{12} = \bold{-1^\circ F}$

Negative sign indicates that the temperature has decreased.
