Can someone find the surface area for me?

9514 1404 393

  876 square inches

Step-by-step explanation:

The total surface area is the sum of the areas of the two triangular bases, and the lateral area--the sum of the areas of the three rectangular faces.

Total triangle area:

  2(1/2)(bh) = bh = (26 in)(6 in) = 156 in²

Rectangular face area is the product of the length of the prism (12 in) and the perimeter of the base:

  (12 in)(26 in + 24 in +  10 in) = (12 in)(60 in) = 720 in²

Total area is then ...

  base area + lateral area = 156 in² +720 in² = 876 in²

Comment on the question

The geometry shown is impossible. The base width must be about 31.24 inches for the other dimensions to be accurate.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
