How do i find surface area of a prism?

Step-by-step explanation:

If you want the surface area of a rectangular prism, then you'll use a formula resembling this:

A = 2(area of end) + 2(area of top) + 2 (area of side).

Example:  suppose the dimensions of the prism are 3 in by 5 in by 8 in.

Then the total surface area is:

A = 2(3*5) + 2(3*8) + 2(5*8) square inches, or 2(15) + 2(48) + 2(40) sq in, or

A = 30 + 96 + 80 sq in, or A = 206 sq in

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
