Surface area is the total area of the surface. A cube has 6 surface, and each surface is the same. Each surface is a 11 by 11 square. Therefore there will be 6 11in. x 11in. surfaces. The math would be 11x11x6 =726.

Answer:

726 in²

Step-by-step explanation:

The surface area of a cube is the area of each side of the cube multiplied by 6 (since the cube has 6 sides).

To know what is the area of each side, the formula is A= l² where l is the length. Therefore we would have that the area is 11²=121.

Now we are going to multiply this number by 6 to find the surface area, SA = 121 x 6 = 726 in²

The cost of a ticket increases by 10% to £18.15 Work out the original cost.

Licemer1 [7]

Answer:

£16.50

Step-by-step explanation:

$x \times (1+\frac{10}{100} )=18.15$

$x \times \frac{110}{100} =18.15$

$\frac{110}{100} x=18.15$

$1.1x=18.15$

$\frac{1.1x}{1.1}=\frac{18.15}{1.1}$

$x=16.5$

On a coordinate grid, your campsite is located at (3, – 5), and the next checkpoint station is located at (–10, 1). Each unit in

Bumek [7]

Answer: A. about 30.8 miles

The x and y distance from the campsite at A (3, – 5), and the next checkpoint station is located at B (–10, 1) would be:
Xab= Xb- Xa= -10 - 3= -13
Yab= Yb- Ya= 1- (-5)= 6

The resultant distance would be
c^2= a^2+b^2
c^2= (-13)^2 + (6)^2
c= √(169+36)= √205
c=14.32

If each unit in the coordinate plane represents 2.15 miles, the true distance= 14.32*2.15 miles= 30.78 miles

Find the area: (I will give brainliest) +50 points.

scZoUnD [109]

Answer:

$A_{total} = 16\ cm^2$

Step-by-step explanation:

Step 1: Determine the area of the top rectangle

We can tell that the total shape seems like two rectangles glued together. We can separate the top rectangle and determine the area of it and then determine the area of the bottom rectangle and combine them. Lets first solve the left rectangle.

$A=l*w$

$A_{top\ rectangle}=6\ cm * 2\ cm$

$A_{top\ rectangle}=12\ cm^2$

Step 2: Determine the area of the bottom rectangle

$A=l*w$

$A_{bottom\ rectangle}=2\ cm * 2\ cm$

$A_{bottom\ rectangle}=4\ cm^2$

Step 3: Determine the total area

$A_{total}=A_{top\ rectangle}+A_{bottom\ rectangle}$

$A_{total}=12\ cm^2+4\ cm^2$

$A_{total} = 16\ cm^2$

Answer: $A_{total} = 16\ cm^2$
