Answer:
C.
Step-by-step explanation:
The formula for surface area is
LA + 2B
LA indicated Lateral Area and can be found multiplying perimeter of base by the height.
7 + 7 + 14 + 14 = 42 * 7 = 294
Multiply the LA from above with the area of base times 2.
98 * 2 = 196
294 + 196 = 490, so the surface area of the rectangular prism is 490 units.

ANSWER
The is 10 is meters
EXPLANATION
The area of a tra-pezoid can be calculated using the formula;
We substitute the values to get,
The height is 10 meters.
A right rectangular prism would have three pairs of identical sides. You need to find the area of each of these sides individually, then add them to find the total surface area of the shape.
The dimensions of the three unique of sides are length x width, width x height, and height x length.
So:
2(6 * 9) + 2(9 * 10) + 2(10 * 6)
2(54) + 2(90) + 2(60)
108 + 180 + 120
= 408 inches^2
