Answer:
248 ft²
Option C
Step-by-step explanation:
The right prism has 6 faces all of rectangular shape
The top and bottom rectangles are 6ft x 4 ft each so the total area of the two top and bottom faces is 2 x 4 x 6 = 48 ft²
The front and back side rectangles have dimensions 10 ft x 6 ft
Total area of both of these front and back spaces = 2 x 10 x 6 = 120 ft²
The left and right faces have dimensions 10 ft x 4 ft
Total area of these two faces = 2 x 10 x 4 = 80 ft²
Total surface area = 48 + 120 + 80 = 248 ft²
