Okay, the easiest way (I personally) find surface area is to find the area of each face [L x W (OR H)] and then add all of the areas together.

Question 1) The Area of 1 of the faces is 4, because 2 x 2 is 4. Since there is 6 faces, do 6 times 4, or $24^{2}$ feet in total.

The equation for surface area of rectangular prisms is 2ab + 2bc + 2ac. The length is a the width is c and the height is b. Plug this in and solve. A=5 B=8 C=3. You should come up about with 2(5)(8) +2(8)(3) + 2(5)(3). This will equal 80 + 48 + 30 = 158 That is your answer.

solmaris [256]

Answer:

$5+2.25m=38.75$

Step-by-step explanation:

Let $m$ represent the number of miles to Jazmin's home.

Initial cost to pick Jazmin $=\$5$

Cost per mile $=\$2.25$

Therefore,

Cost for $m$ miles $=\$2.25m$

Total cost of Jazmin's ride = Initial cost to pick Jazmin + Cost for $m$ miles

= $5+2.25m$

Also, total cost incurred $=\$38.75$

So, equation that represent the above situation is $5+2.25m=38.75$

4.75 is your answer because you add 2,8,10,12 and then divide it by 4 equals 8 . Then divide 2,8,10,12 by 8 gives you the total of 6,0,9,4 add all that gives you a total of 19/4 equals your answer of 4.75
