Answer:

13.9 (if x is the Hypotenuse)

Step-by-step explanation:

which one is the Hypotenuse (the side opposite of the 90 degree angle) ?

because that determines the calculation.

if x is the Hypotenuse then Pythagoras looks like this

x² = 7² + 12² = 49 + 144 = 193

x = sqrt(193) = 13.9

if 12 is the Hypotenuse, then it looks like this

12² = 7² + x²

144 = 49 + x²

95 = x²

x = sqrt(95) = 9.75

(Quick please ) !!!!!!!!!!!!!!!! Help me!!!!! find the surface area of the rectangular prism!!!!!! thank you
Aleks [24]
You can do this !

The rectangular prism has

                   -- length = 10 cm
                   -- width  =  7 cm
                   -- height =  3 cm.

-- The area of the top and bottom is  (length x width)  each.

-- The area of the left and right sides is  (length x height)  each.

-- The area of the front and back is  (width x height)  each.

There.  I just laid out all the schmartz you need to answer this question.
The rest is all simple arithmetic, and you're perfectly capable of turning
the crank and getting the answer.  You don't need anybody else to do
that part for you.

Don't forget your units.  The area of each flat face is (cm) times (cm),
and that product will be some cm² , for area.
