Question

What is the surface area of a rectangular prism that is 15 centimeters long, 13 centimeters wide, and 8 centimeters high? (1 point)
A) 419 square centimeters
B) 780 square centimeters
C) 838 square centimeters
D) 1,560 square centimeters

Answer 1

The surface area of a rectangular prism is given by the formula SA = 2lw + 2lh + 2wh, where l, w, and h are the length, width, and height of the prism respectively. Plugging in the given values, we get:

SA = 2(15)(13) + 2(15)(8) + 2(13)(8)
SA = 390 + 240 + 208
SA = 838

Therefore, the surface area of the rectangular prism is 838 square centimeters, and the answer is C) 838 square centimeters.
