Answer:

384\ in^{2}

Step-by-step explanation:

Hello, I think I can help you with this

Let's remember

the area of a square is = side * side=side2

the number of faces of a cube = 6

So, the total area of a cube will be

the area of a square*the number of faces of a cube=side*side*6

A_{t}=side^{2} *6\\

Step 2

put the values into the equation

let

side = 8 in

A_{t}=side^{2} *6\\A_{t}=( 8\ inch)^{2} *6\\A_{t}=64\ inch^{2} *6\\\ A_{t}=384\ inch^{2}

Have a great day

The surface area is the sum of the are of all sides. One side's area is 64 in^2 and since it's a cube, all sides will be the same.
64*6 = 384
The surface area is 384 in^2

A tortoise makes a journey in two parts; it can either walk at 4cm/s or crawl at 3cm/s. If the tottoise walks the first part and
Ugo [173]

Answer:

120

240

Step-by-step explanation:

We call the length of first part x

Length of second part = y

In the first scenario, it took the tortoise 110 sec to walk the first part and crawl the second.

So,

We have this equation,

x/4 + y/3 = 110

We take the LCM

(3x + 4y)/12 = 110

When we cross multiply

3x + 4y = 110x12

3x + 4y = 1320 ----- equation 1

For scenario 2

x/3 + y/4 = 100

When we take the LCM

(4x + 3y)/12 = 100

We cross multiply

4x + 3y = 100x12

4x + 3y = 1200 ------ equation 2

We now have two equations and we will solve for x and y using simultaneous linear equation.

3x + 4y = 1320 ----- 1

4x + 3y = 1200 ----- 2

We subtract equation 2 from 1 to get

- x + y = 120

We make y subject

y = x + 120 ----- 3

We put the value of y in equation 3 into equation 1

3x + 4(x + 120) = 1320

3x + 4x + 480 = 1320

7x + 480 = 1320

7x = 1320-480

7x = 840

We divide through by 7

x = 840/7

x = 120

We put value of x in equation 3

y = x + 120

y = 120 + 120

y = 240

120 and 240 are the lengths of the 2 parts of the journey.

Thanks
