Option C.
Step-by-step explanation:
It is given that the surface area of a rectangular prism, is
where a, b, and c represent the lengths of the edges of the prism.
We need to find the surface area of this prism if a = 12 inches, b = 6 inches, and c = 4 inches.
Substitute a=12, b=6 and c=4 in the above formula.
The surface area of this prism is 288 sq.inches.
Therefore, the correct option is C.
Area of Trapezoid
where B = larger base, b = smaller base, and h = height.
For this trapezoid, you have
B = 10 + 7 + 7 = 24
b = 10
h = 9
where B = larger base, b = smaller base, and h = height.
For this trapezoid, you have
B = 10 + 7 + 7 = 24
b = 10
h = 9
